Enum hyper::header::Range
[−]
[src]
pub enum Range { Bytes(Vec<ByteRangeSpec>), Unregistered(String, String), }
Range
header, defined in RFC7233
The "Range" header field on a GET request modifies the method semantics to request transfer of only one or more subranges of the selected representation data, rather than the entire selected representation data.
ABNF
Range = byte-ranges-specifier / other-ranges-specifier
other-ranges-specifier = other-range-unit "=" other-range-set
other-range-set = 1*VCHAR
bytes-unit = "bytes"
byte-ranges-specifier = bytes-unit "=" byte-range-set
byte-range-set = 1#(byte-range-spec / suffix-byte-range-spec)
byte-range-spec = first-byte-pos "-" [last-byte-pos]
first-byte-pos = 1*DIGIT
last-byte-pos = 1*DIGIT
Example values
bytes=1000-
bytes=-2000
bytes=0-1,30-40
bytes=0-10,20-90,-100
custom_unit=0-123
custom_unit=xxx-yyy
Examples
use hyper::header::{Headers, Range, ByteRangeSpec}; let mut headers = Headers::new(); headers.set(Range::Bytes( vec![ByteRangeSpec::FromTo(1, 100), ByteRangeSpec::AllFrom(200)] )); headers.clear(); headers.set(Range::Unregistered("letters".to_owned(), "a-f".to_owned()));
use hyper::header::{Headers, Range}; let mut headers = Headers::new(); headers.set(Range::bytes(1, 100)); headers.clear(); headers.set(Range::bytes_multi(vec![(1, 100), (200, 300)]));
Variants
Bytes(Vec<ByteRangeSpec>)

Methods
impl Range
[src]
fn bytes(from: u64, to: u64) -> Range
[src]
Get the most common byte range header ("bytes=from-to")
fn bytes_multi(ranges: Vec<(u64, u64)>) -> Range
[src]
Get byte range header with multiple subranges ("bytes=from1-to1,from2-to2,fromX-toX")
