Struct bytes::Bytes
[−]
[src]
pub struct Bytes { /* fields omitted */ }
A reference counted contiguous slice of memory.
Bytes
is an efficient container for storing and operating on contiguous
slices of memory. It is intended for use primarily in networking code, but
could have applications elsewhere as well.
Bytes
values facilitate zero-copy network programming by allowing multiple
Bytes
objects to point to the same underlying memory. This is managed by
using a reference count to track when the memory is no longer needed and can
be freed.
use bytes::Bytes; let mut mem = Bytes::from(&b"Hello world"[..]); let a = mem.slice(0, 5); assert_eq!(&a[..], b"Hello"); let b = mem.split_to(6); assert_eq!(&mem[..], b"world"); assert_eq!(&b[..], b"Hello ");
Memory layout
The Bytes
struct itself is fairly small, limited to a pointer to the
memory and 4 usize
fields used to track information about which segment of
the underlying memory the Bytes
handle has access to.
The memory layout looks like this:
+-------+
| Bytes |
+-------+
/ \_____
| \
v v
+-----+------------------------------------+
| Arc | | Data | |
+-----+------------------------------------+
Bytes
keeps both a pointer to the shared Arc
containing the full memory
slice and a pointer to the start of the region visible by the handle.
Bytes
also tracks the length of its view into the memory.
Sharing
The memory itself is reference counted, and multiple Bytes
objects may
point to the same region. Each Bytes
handle point to different sections within
the memory region, and Bytes
handle may or may not have overlapping views
into the memory.
Arc ptrs +---------+
________________________ / | Bytes 2 |
/ +---------+
/ +-----------+ | |
|_________/ | Bytes 1 | | |
| +-----------+ | |
| | | ___/ data | tail
| data | tail |/ |
v v v v
+-----+---------------------------------+-----+
| Arc | | | | |
+-----+---------------------------------+-----+
Mutating
While Bytes
handles may potentially represent overlapping views of the
underlying memory slice and may not be mutated, BytesMut
handles are
guaranteed to be the only handle able to view that slice of memory. As such,
BytesMut
handles are able to mutate the underlying memory. Note that
holding a unique view to a region of memory does not mean that there are no
other Bytes
and BytesMut
handles with disjoint views of the underlying
memory.
Inline bytes
As an optimization, when the slice referenced by a Bytes
or BytesMut
handle is small enough [1], Bytes
will avoid the allocation by inlining
the slice directly in the handle. In this case, a clone is no longer
"shallow" and the data will be copied.
[1] Small enough: 31 bytes on 64 bit systems, 15 on 32 bit systems.
Methods
impl Bytes
[src]
fn with_capacity(capacity: usize) -> Bytes
[src]
Creates a new Bytes
with the specified capacity.
The returned Bytes
will be able to hold at least capacity
bytes
without reallocating. If capacity
is under 3 * size_of::<usize>()
,
then BytesMut
will not allocate.
It is important to note that this function does not specify the length
of the returned Bytes
, but only the capacity.
Examples
use bytes::Bytes; let mut bytes = Bytes::with_capacity(64); // `bytes` contains no data, even though there is capacity assert_eq!(bytes.len(), 0); bytes.extend_from_slice(&b"hello world"[..]); assert_eq!(&bytes[..], b"hello world");
fn new() -> Bytes
[src]
Creates a new empty Bytes
.
This will not allocate and the returned Bytes
handle will be empty.
Examples
use bytes::Bytes; let b = Bytes::new(); assert_eq!(&b[..], b"");
fn from_static(bytes: &'static [u8]) -> Bytes
[src]
Creates a new Bytes
from a static slice.
The returned Bytes
will point directly to the static slice. There is
no allocating or copying.
Examples
use bytes::Bytes; let b = Bytes::from_static(b"hello"); assert_eq!(&b[..], b"hello");
fn len(&self) -> usize
[src]
Returns the number of bytes contained in this Bytes
.
Examples
use bytes::Bytes; let b = Bytes::from(&b"hello"[..]); assert_eq!(b.len(), 5);
fn is_empty(&self) -> bool
[src]
Returns true if the Bytes
has a length of 0.
Examples
use bytes::Bytes; let b = Bytes::new(); assert!(b.is_empty());
fn slice(&self, begin: usize, end: usize) -> Bytes
[src]
Returns a slice of self for the index range [begin..end)
.
This will increment the reference count for the underlying memory and
return a new Bytes
handle set to the slice.
This operation is O(1)
.
Examples
use bytes::Bytes; let a = Bytes::from(&b"hello world"[..]); let b = a.slice(2, 5); assert_eq!(&b[..], b"llo");
Panics
Requires that begin <= end
and end <= self.len()
, otherwise slicing
will panic.
fn slice_from(&self, begin: usize) -> Bytes
[src]
Returns a slice of self for the index range [begin..self.len())
.
This will increment the reference count for the underlying memory and
return a new Bytes
handle set to the slice.
This operation is O(1)
and is equivalent to self.slice(begin, self.len())
.
Examples
use bytes::Bytes; let a = Bytes::from(&b"hello world"[..]); let b = a.slice_from(6); assert_eq!(&b[..], b"world");
Panics
Requires that begin <= self.len()
, otherwise slicing will panic.
fn slice_to(&self, end: usize) -> Bytes
[src]
Returns a slice of self for the index range [0..end)
.
This will increment the reference count for the underlying memory and
return a new Bytes
handle set to the slice.
This operation is O(1)
and is equivalent to self.slice(0, end)
.
Examples
use bytes::Bytes; let a = Bytes::from(&b"hello world"[..]); let b = a.slice_to(5); assert_eq!(&b[..], b"hello");
Panics
Requires that end <= self.len()
, otherwise slicing will panic.
fn split_off(&mut self, at: usize) -> Bytes
[src]
Splits the bytes into two at the given index.
Afterwards self
contains elements [0, at)
, and the returned Bytes
contains elements [at, len)
.
This is an O(1)
operation that just increases the reference count and
sets a few indices.
Examples
use bytes::Bytes; let mut a = Bytes::from(&b"hello world"[..]); let b = a.split_off(5); assert_eq!(&a[..], b"hello"); assert_eq!(&b[..], b" world");
Panics
Panics if at > len
.
fn split_to(&mut self, at: usize) -> Bytes
[src]
Splits the bytes into two at the given index.
Afterwards self
contains elements [at, len)
, and the returned
Bytes
contains elements [0, at)
.
This is an O(1)
operation that just increases the reference count and
sets a few indices.
Examples
use bytes::Bytes; let mut a = Bytes::from(&b"hello world"[..]); let b = a.split_to(5); assert_eq!(&a[..], b" world"); assert_eq!(&b[..], b"hello");
Panics
Panics if at > len
.
fn truncate(&mut self, len: usize)
[src]
Shortens the buffer, keeping the first len
bytes and dropping the
rest.
If len
is greater than the buffer's current length, this has no
effect.
The split_off
method can emulate truncate
, but this causes the
excess bytes to be returned instead of dropped.
Examples
use bytes::Bytes; let mut buf = Bytes::from(&b"hello world"[..]); buf.truncate(5); assert_eq!(buf, b"hello"[..]);
fn clear(&mut self)
[src]
Clears the buffer, removing all data.
Examples
use bytes::Bytes; let mut buf = Bytes::from(&b"hello world"[..]); buf.clear(); assert!(buf.is_empty());
fn try_mut(self) -> Result<BytesMut, Bytes>
[src]
Attempts to convert into a BytesMut
handle.
This will only succeed if there are no other outstanding references to
the underlying chunk of memory. Bytes
handles that contain inlined
bytes will always be convertable to BytesMut
.
Examples
use bytes::Bytes; let a = Bytes::from(&b"Mary had a little lamb, little lamb, little lamb..."[..]); // Create a shallow clone let b = a.clone(); // This will fail because `b` shares a reference with `a` let a = a.try_mut().unwrap_err(); drop(b); // This will succeed let mut a = a.try_mut().unwrap(); a[0] = b'b'; assert_eq!(&a[..4], b"bary");
fn extend_from_slice(&mut self, extend: &[u8])
[src]
Appends given bytes to this object.
If this Bytes
object has not enough capacity, it is resized first.
If it is shared (refcount > 1
), it is copied first.
This operation can be less effective than the similar operation on
BytesMut
, especially on small additions.
Examples
use bytes::Bytes; let mut buf = Bytes::from("aabb"); buf.extend_from_slice(b"ccdd"); buf.extend_from_slice(b"eeff"); assert_eq!(b"aabbccddeeff", &buf[..]);

fn get<I>(&self, index: I) -> Option<&<I as SliceIndex<[T]>>::Output> where
I: SliceIndex<[T]>,
1.0.0[src]
I: SliceIndex<[T]>,
Returns a reference to an element or subslice depending on the type of index.

position or
None
if out of bounds. - If given a range, returns the subslice corresponding to that range,
or

unsafe fn get_unchecked<I>(&self, index: I) -> &<I as SliceIndex<[T]>>::Output where
I: SliceIndex<[T]>,
1.0.0[src]
I: SliceIndex<[T]>,
Returns a reference to an element or subslice, without doing bounds checking.
This is generally not recommended, use with caution! For a safe
alternative see get
.
Examples
let x = &[1, 2, 4]; unsafe { assert_eq!(x.get_unchecked(1), &2); }
fn as_ptr(&self) -> *const T
1.0.0[src]
Returns a raw pointer to the slice's buffer.
The caller must ensure that the slice outlives the pointer this function returns, or else it will end up pointing to garbage.
Modifying the container referenced by this slice may cause its buffer to be reallocated, which would also make any pointers to it invalid.
Examples
let x = &[1, 2, 4]; let x_ptr = x.as_ptr(); unsafe { for i in 0..x.len() { assert_eq!(x.get_unchecked(i), &*x_ptr.offset(i as isize)); } }

Returns an iterator over the slice.
Examples
let x = &[1, 2, 4]; let mut iterator = x.iter(); assert_eq!(iterator.next(), Some(&1)); assert_eq!(iterator.next(), Some(&2)); assert_eq!(iterator.next(), Some(&4)); assert_eq!(iterator.next(), None);
fn windows(&self, size: usize) -> Windows<T>
1.0.0[src]
Returns an iterator over all contiguous windows of length
size
. The windows overlap. If the slice is shorter than
size
, the iterator returns no values.
Panics
Panics if size
is 0.
Examples
let slice = ['r', 'u', 's', 't']; let mut iter = slice.windows(2); assert_eq!(iter.next().unwrap(), &['r', 'u']); assert_eq!(iter.next().unwrap(), &['u', 's']); assert_eq!(iter.next().unwrap(), &['s', 't']); assert!(iter.next().is_none());
If the slice is shorter than size
:
let slice = ['f', 'o', 'o']; let mut iter = slice.windows(4); assert!(iter.next().is_none());
fn chunks(&self, size: usize) -> Chunks<T>
1.0.0[src]
Returns an iterator over size
elements of the slice at a
time. The chunks are slices and do not overlap. If size
does
not divide the length of the slice, then the last chunk will
not have length size
.
Panics
Panics if size
is 0.
Examples
let slice = ['l', 'o', 'r', 'e', 'm']; let mut iter = slice.chunks(2); assert_eq!(iter.next().unwrap(), &['l', 'o']); assert_eq!(iter.next().unwrap(), &['r', 'e']); assert_eq!(iter.next().unwrap(), &['m']); assert!(iter.next().is_none());
fn split_at(&self, mid: usize) -> (&[T], &[T])
1.0.0[src]
Divides one slice into two at an index.
The first will contain all indices from [0, mid)
(excluding
the index mid
itself) and the second will contain all
indices from [mid, len)
(excluding the index len
itself).
Panics
Panics if mid > len
.
Examples
let v = [10, 40, 30, 20, 50]; let (v1, v2) = v.split_at(2); assert_eq!([10, 40], v1); assert_eq!([30, 20, 50], v2);
fn split<F>(&self, pred: F) -> Split<T, F> where
F: FnMut(&T) -> bool,
1.0.0[src]
F: FnMut(&T) -> bool,
Returns an iterator over subslices separated by elements that match
pred
. The matched element is not contained in the subslices.
Examples
let slice = [10, 40, 33, 20]; let mut iter = slice.split(|num| num % 3 == 0); assert_eq!(iter.next().unwrap(), &[10, 40]); assert_eq!(iter.next().unwrap(), &[20]); assert!(iter.next().is_none());
If the first element is matched, an empty slice will be the first item returned by the iterator. Similarly, if the last element in the slice is matched, an empty slice will be the last item returned by the iterator:
let slice = [10, 40, 33]; let mut iter = slice.split(|num| num % 3 == 0); assert_eq!(iter.next().unwrap(), &[10, 40]); assert_eq!(iter.next().unwrap(), &[]); assert!(iter.next().is_none());
If two matched elements are directly adjacent, an empty slice will be present between them:
let slice = [10, 6, 33, 20]; let mut iter = slice.split(|num| num % 3 == 0); assert_eq!(iter.next().unwrap(), &[10]); assert_eq!(iter.next().unwrap(), &[]); assert_eq!(iter.next().unwrap(), &[20]); assert!(iter.next().is_none());
fn rsplit<F>(&self, pred: F) -> RSplit<T, F> where
F: FnMut(&T) -> bool,
[src]
F: FnMut(&T) -> bool,
slice_rsplit
)Returns an iterator over subslices separated by elements that match
pred
, starting at the end of the slice and working backwards.
The matched element is not contained in the subslices.
Examples
#![feature(slice_rsplit)] let slice = [11, 22, 33, 0, 44, 55]; let mut iter = slice.rsplit(|num| *num == 0); assert_eq!(iter.next().unwrap(), &[44, 55]); assert_eq!(iter.next().unwrap(), &[11, 22, 33]); assert_eq!(iter.next(), None);
As with split()
, if the first or last element is matched, an empty
slice will be the first (or last) item returned by the iterator.
#![feature(slice_rsplit)] let v = &[0, 1, 1, 2, 3, 5, 8]; let mut it = v.rsplit(|n| *n % 2 == 0); assert_eq!(it.next().unwrap(), &[]); assert_eq!(it.next().unwrap(), &[3, 5]); assert_eq!(it.next().unwrap(), &[1, 1]); assert_eq!(it.next().unwrap(), &[]); assert_eq!(it.next(), None);
fn splitn<F>(&self, n: usize, pred: F) -> SplitN<T, F> where
F: FnMut(&T) -> bool,
1.0.0[src]
F: FnMut(&T) -> bool,
Returns an iterator over subslices separated by elements that match
pred
, limited to returning at most n
items. The matched element is
not contained in the subslices.
The last element returned, if any, will contain the remainder of the slice.
Examples
Print the slice split once by numbers divisible by 3 (i.e. [10, 40]
,
[20, 60, 50]
):
let v = [10, 40, 30, 20, 60, 50]; for group in v.splitn(2, |num| *num % 3 == 0) { println!("{:?}", group); }
fn rsplitn<F>(&self, n: usize, pred: F) -> RSplitN<T, F> where
F: FnMut(&T) -> bool,
1.0.0[src]
F: FnMut(&T) -> bool,
Returns an iterator over subslices separated by elements that match
pred
limited to returning at most n
items. This starts at the end of
the slice and works backwards. The matched element is not contained in
the subslices.
The last element returned, if any, will contain the remainder of the slice.
Examples
Print the slice split once, starting from the end, by numbers divisible
by 3 (i.e. [50]
, [10, 40, 30, 20]
):
let v = [10, 40, 30, 20, 60, 50]; for group in v.rsplitn(2, |num| *num % 3 == 0) { println!("{:?}", group); }
fn contains(&self, x: &T) -> bool where
T: PartialEq<T>,
1.0.0[src]
T: PartialEq<T>,
Returns true
if the slice contains an element with the given value.
Examples
let v = [10, 40, 30]; assert!(v.contains(&30)); assert!(!v.contains(&50));
fn starts_with(&self, needle: &[T]) -> bool where
T: PartialEq<T>,
1.0.0[src]
T: PartialEq<T>,
Returns true
if needle
is a prefix of the slice.
Examples
let v = [10, 40, 30]; assert!(v.starts_with(&[10])); assert!(v.starts_with(&[10, 40])); assert!(!v.starts_with(&[50])); assert!(!v.starts_with(&[10, 50]));
Always returns true
if needle
is an empty slice:
let v = &[10, 40, 30]; assert!(v.starts_with(&[])); let v: &[u8] = &[]; assert!(v.starts_with(&[]));
fn ends_with(&self, needle: &[T]) -> bool where
T: PartialEq<T>,
1.0.0[src]
T: PartialEq<T>,
Returns true
if needle
is a suffix of the slice.
Examples
let v = [10, 40, 30]; assert!(v.ends_with(&[30])); assert!(v.ends_with(&[40, 30])); assert!(!v.ends_with(&[50])); assert!(!v.ends_with(&[50, 30]));
Always returns true
if needle
is an empty slice:
let v = &[10, 40, 30]; assert!(v.ends_with(&[])); let v: &[u8] = &[]; assert!(v.ends_with(&[]));
fn binary_search(&self, x: &T) -> Result<usize, usize> where
T: Ord,
1.0.0[src]
T: Ord,
Binary searches this sorted slice for a given element.
If the value is found then Ok
is returned, containing the
index of the matching element; if the value is not found then
Err
is returned, containing the index where a matching
element could be inserted while maintaining sorted order.
Examples
Looks up a series of four elements. The first is found, with a
uniquely determined position; the second and third are not
found; the fourth could match any position in [1, 4]
.
let s = [0, 1, 1, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]; assert_eq!(s.binary_search(&13), Ok(9)); assert_eq!(s.binary_search(&4), Err(7)); assert_eq!(s.binary_search(&100), Err(13)); let r = s.binary_search(&1); assert!(match r { Ok(1...4) => true, _ => false, });
fn binary_search_by<'a, F>(&'a self, f: F) -> Result<usize, usize> where
F: FnMut(&'a T) -> Ordering,
1.0.0[src]
F: FnMut(&'a T) -> Ordering,
Binary searches this sorted slice with a comparator function.
The comparator function should implement an order consistent
with the sort order of the underlying slice, returning an
order code that indicates whether its argument is Less
,
Equal
or Greater
the desired target.
If a matching value is found then returns Ok
, containing
the index for the matched element; if no match is found then
Err
is returned, containing the index where a matching
element could be inserted while maintaining sorted order.
Examples
Looks up a series of four elements. The first is found, with a
uniquely determined position; the second and third are not
found; the fourth could match any position in [1, 4]
.
let s = [0, 1, 1, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]; let seek = 13; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Ok(9)); let seek = 4; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Err(7)); let seek = 100; assert_eq!(s.binary_search_by(|probe| probe.cmp(&seek)), Err(13)); let seek = 1; let r = s.binary_search_by(|probe| probe.cmp(&seek)); assert!(match r { Ok(1...4) => true, _ => false, });
fn binary_search_by_key<'a, B, F>(&'a self, b: &B, f: F) -> Result<usize, usize> where
B: Ord,
F: FnMut(&'a T) -> B,
1.10.0[src]
B: Ord,
F: FnMut(&'a T) -> B,
Binary searches this sorted slice with a key extraction function.
Assumes that the slice is sorted by the key, for instance with
sort_by_key
using the same key extraction function.
If a matching value is found then returns Ok
, containing the
index for the matched element; if no match is found then Err
is returned, containing the index where a matching element could
be inserted while maintaining sorted order.
Examples
Looks up a series of four elements in a slice of pairs sorted by
their second elements. The first is found, with a uniquely
determined position; the second and third are not found; the
fourth could match any position in [1, 4]
.
let s = [(0, 0), (2, 1), (4, 1), (5, 1), (3, 1), (1, 2), (2, 3), (4, 5), (5, 8), (3, 13), (1, 21), (2, 34), (4, 55)]; assert_eq!(s.binary_search_by_key(&13, |&(a,b)| b), Ok(9)); assert_eq!(s.binary_search_by_key(&4, |&(a,b)| b), Err(7)); assert_eq!(s.binary_search_by_key(&100, |&(a,b)| b), Err(13)); let r = s.binary_search_by_key(&1, |&(a,b)| b); assert!(match r { Ok(1...4) => true, _ => false, });
fn to_vec(&self) -> Vec<T> where
T: Clone,
1.0.0[src]
T: Clone,
Copies self
into a new Vec
.
Examples
let s = [10, 40, 30]; let x = s.to_vec(); // Here, `s` and `x` can be modified independently.
