Enum rocket::http::hyper::header::Range[−][src]

pub enum Range {
    Bytes(Vec<ByteRangeSpec, Global>),
    Unregistered(String, String),
}
Expand description

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

Byte range

Unregistered(String, String)

Custom range, with unit not registered at IANA (other-range-unit: String , other-range-set: String)

Implementations

impl Range[src]

pub fn bytes(from: u64, to: u64) -> Range[src]

pub fn bytes_multi(ranges: Vec<(u64, u64), Global>) -> Range[src]

Get byte range header with multiple subranges (“bytes=from1-to1,from2-to2,fromX-toX”)
