Struct hyper::header::ContentLocation
[−]
[src]
pub struct ContentLocation(pub String);
Content-Location
header, defined in
RFC7231
The header can be used by both the client in requests and the server
in responses with different semantics. Client sets Content-Location
to refer to the URI where original representation of the body was
obtained.
In responses Content-Location
represents URI for the representation
that was content negotiated, created or for the response payload.
ABNF
Content-Location = absolute-URI / partial-URI
Example values
/hypertext/Overview.html
http://www.example.org/hypertext/Overview.html
Examples
use hyper::header::{Headers, ContentLocation}; let mut headers = Headers::new(); headers.set(ContentLocation("/hypertext/Overview.html".to_owned()));
use hyper::header::{Headers, ContentLocation}; let mut headers = Headers::new(); headers.set(ContentLocation("http://www.example.org/hypertext/Overview.html".to_owned()));
Methods from Deref<Target = String>
fn into_bytes(self) -> Vec<u8>
1.0.0[src]
Converts a String
into a byte vector.
This consumes the String
, so we do not need to copy its contents.
Examples
Basic usage:
let s = String::from("hello"); let bytes = s.into_bytes(); assert_eq!(&[104, 101, 108, 108, 111][..], &bytes[..]);
fn as_str(&self) -> &str
1.7.0[src]
Extracts a string slice containing the entire string.
fn as_mut_str(&mut self) -> &mut str
1.7.0[src]
Extracts a string slice containing the entire string.
fn push_str(&mut self, string: &str)
1.0.0[src]
Appends a given string slice onto the end of this String
.
Examples
Basic usage:
let mut s = String::from("foo"); s.push_str("bar"); assert_eq!("foobar", s);
fn capacity(&self) -> usize
1.0.0[src]
Returns this String
's capacity, in bytes.
Examples
Basic usage:
let s = String::with_capacity(10); assert!(s.capacity() >= 10);
fn reserve(&mut self, additional: usize)
1.0.0[src]
Ensures that this String
's capacity is at least additional
bytes
larger than its length.
The capacity may be increased by more than additional
bytes if it
chooses, to prevent frequent reallocations.
If you do not want this "at least" behavior, see the reserve_exact
method.
Panics
Panics if the new capacity overflows usize
.
Examples
Basic usage:
let mut s = String::new(); s.reserve(10); assert!(s.capacity() >= 10);
This may not actually increase the capacity:
let mut s = String::with_capacity(10); s.push('a'); s.push('b'); // s now has a length of 2 and a capacity of 10 assert_eq!(2, s.len()); assert_eq!(10, s.capacity()); // Since we already have an extra 8 capacity, calling this... s.reserve(8); // ... doesn't actually increase. assert_eq!(10, s.capacity());
fn reserve_exact(&mut self, additional: usize)
1.0.0[src]
Ensures that this String
's capacity is additional
bytes
larger than its length.
Consider using the reserve
method unless you absolutely know
better than the allocator.
Panics
Panics if the new capacity overflows usize
.
Examples
Basic usage:
let mut s = String::new(); s.reserve_exact(10); assert!(s.capacity() >= 10);
This may not actually increase the capacity:
let mut s = String::with_capacity(10); s.push('a'); s.push('b'); // s now has a length of 2 and a capacity of 10 assert_eq!(2, s.len()); assert_eq!(10, s.capacity()); // Since we already have an extra 8 capacity, calling this... s.reserve_exact(8); // ... doesn't actually increase. assert_eq!(10, s.capacity());
fn shrink_to_fit(&mut self)
1.0.0[src]
Shrinks the capacity of this String
to match its length.
Examples
Basic usage:
let mut s = String::from("foo"); s.reserve(100); assert!(s.capacity() >= 100); s.shrink_to_fit(); assert_eq!(3, s.capacity());
fn push(&mut self, ch: char)
1.0.0[src]
Appends the given char
to the end of this String
.
Examples
Basic usage:
let mut s = String::from("abc"); s.push('1'); s.push('2'); s.push('3'); assert_eq!("abc123", s);
fn as_bytes(&self) -> &[u8]
1.0.0[src]
Returns a byte slice of this String
's contents.
The inverse of this method is from_utf8
.
Examples
Basic usage:
let s = String::from("hello"); assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());
fn truncate(&mut self, new_len: usize)
1.0.0[src]
Shortens this String
to the specified length.
If new_len
is greater than the string's current length, this has no
effect.
Note that this method has no effect on the allocated capacity of the string
Panics
Panics if new_len
does not lie on a char
boundary.
Examples
Basic usage:
let mut s = String::from("hello"); s.truncate(2); assert_eq!("he", s);
fn pop(&mut self) -> Option<char>
1.0.0[src]
Removes the last character from the string buffer and returns it.
Returns None
if this String
is empty.
Examples
Basic usage:
let mut s = String::from("foo"); assert_eq!(s.pop(), Some('o')); assert_eq!(s.pop(), Some('o')); assert_eq!(s.pop(), Some('f')); assert_eq!(s.pop(), None);
fn remove(&mut self, idx: usize) -> char
1.0.0[src]
Removes a char
from this String
at a byte position and returns it.
This is an O(n)
operation, as it requires copying every element in the
buffer.
Panics
Panics if idx
is larger than or equal to the String
's length,
or if it does not lie on a char
boundary.
Examples
Basic usage:
let mut s = String::from("foo"); assert_eq!(s.remove(0), 'f'); assert_eq!(s.remove(1), 'o'); assert_eq!(s.remove(0), 'o');
fn retain<F>(&mut self, f: F) where
F: FnMut(char) -> bool,
[src]
F: FnMut(char) -> bool,
string_retain
)Retains only the characters specified by the predicate.
In other words, remove all characters c
such that f(c)
returns false
.
This method operates in place and preserves the order of the retained
characters.
Examples
#![feature(string_retain)] let mut s = String::from("f_o_ob_ar"); s.retain(|c| c != '_'); assert_eq!(s, "foobar");
fn insert(&mut self, idx: usize, ch: char)
1.0.0[src]
Inserts a character into this String
at a byte position.
This is an O(n)
operation as it requires copying every element in the
buffer.
Panics
Panics if idx
is larger than the String
's length, or if it does not
lie on a char
boundary.
Examples
Basic usage:
let mut s = String::with_capacity(3); s.insert(0, 'f'); s.insert(1, 'o'); s.insert(2, 'o'); assert_eq!("foo", s);
fn insert_str(&mut self, idx: usize, string: &str)
1.16.0[src]
Inserts a string slice into this String
at a byte position.
This is an O(n)
operation as it requires copying every element in the
buffer.
Panics
Panics if idx
is larger than the String
's length, or if it does not
lie on a char
boundary.
Examples
Basic usage:
let mut s = String::from("bar"); s.insert_str(0, "foo"); assert_eq!("foobar", s);
unsafe fn as_mut_vec(&mut self) -> &mut Vec<u8>
1.0.0[src]
Returns a mutable reference to the contents of this String
.
Safety
This function is unsafe because it does not check that the bytes passed
to it are valid UTF-8. If this constraint is violated, it may cause
memory unsafety issues with future users of the String
, as the rest of
the standard library assumes that String
s are valid UTF-8.
Examples
Basic usage:
let mut s = String::from("hello"); unsafe { let vec = s.as_mut_vec(); assert_eq!(&[104, 101, 108, 108, 111][..], &vec[..]); vec.reverse(); } assert_eq!(s, "olleh");
fn len(&self) -> usize
1.0.0[src]
Returns the length of this String
, in bytes.
Examples
Basic usage:
let a = String::from("foo"); assert_eq!(a.len(), 3);
fn is_empty(&self) -> bool
1.0.0[src]
Returns true
if this String
has a length of zero.
Returns false
otherwise.
Examples
Basic usage:
let mut v = String::new(); assert!(v.is_empty()); v.push('a'); assert!(!v.is_empty());
fn split_off(&mut self, at: usize) -> String
1.16.0[src]
Splits the string into two at the given index.
Returns a newly allocated String
. self
contains bytes [0, at)
, and
the returned String
contains bytes [at, len)
. at
must be on the
boundary of a UTF-8 code point.
Note that the capacity of self
does not change.
Panics
Panics if at
is not on a UTF-8
code point boundary, or if it is beyond the last
code point of the string.
Examples
let mut hello = String::from("Hello, World!"); let world = hello.split_off(7); assert_eq!(hello, "Hello, "); assert_eq!(world, "World!");
fn clear(&mut self)
1.0.0[src]
Truncates this String
, removing all contents.
While this means the String
will have a length of zero, it does not
touch its capacity.
Examples
Basic usage:
let mut s = String::from("foo"); s.clear(); assert!(s.is_empty()); assert_eq!(0, s.len()); assert_eq!(3, s.capacity());
fn drain<R>(&mut self, range: R) -> Drain where
R: RangeArgument<usize>,
1.6.0[src]
R: RangeArgument<usize>,
Creates a draining iterator that removes the specified range in the string and yields the removed chars.
Note: The element range is removed even if the iterator is not consumed until the end.
Panics
Panics if the starting point or end point do not lie on a char
boundary, or if they're out of bounds.
Examples
Basic usage:
let mut s = String::from("α is alpha, β is beta"); let beta_offset = s.find('β').unwrap_or(s.len()); // Remove the range up until the β from the string let t: String = s.drain(..beta_offset).collect(); assert_eq!(t, "α is alpha, "); assert_eq!(s, "β is beta"); // A full range clears the string s.drain(..); assert_eq!(s, "");
fn splice<R>(&'a mut self, range: R, replace_with: &'b str) -> Splice<'a, 'b> where
R: RangeArgument<usize>,
[src]
R: RangeArgument<usize>,
🔬 This is a nightly-only experimental API. (splice
)
recently added
Creates a splicing iterator that removes the specified range in the string, replaces with the given string, and yields the removed chars. The given string doesn’t need to be the same length as the range.
Note: The element range is removed when the Splice
is dropped,
even if the iterator is not consumed until the end.
Panics
Panics if the starting point or end point do not lie on a char
boundary, or if they're out of bounds.
Examples
Basic usage:
#![feature(splice)] let mut s = String::from("α is alpha, β is beta"); let beta_offset = s.find('β').unwrap_or(s.len()); // Replace the range up until the β from the string let t: String = s.splice(..beta_offset, "Α is capital alpha; ").collect(); assert_eq!(t, "α is alpha, "); assert_eq!(s, "Α is capital alpha; β is beta");
