Struct headers::Range

pub struct Range(HeaderValue);

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

Examples

use headers::Range;


let range = Range::bytes(0..1234).unwrap();

Tuple Fields

0: HeaderValue

Implementations

impl Range

pub fn bytes(bounds: impl RangeBounds<u64>) -> Result<Self, InvalidRange>

Creates a Range header from bounds.

pub fn iter<'a>(&'a self) -> impl Iterator<Item = (Bound<u64>, Bound<u64>)> + 'a

Iterate the range sets as a tuple of bounds.

Trait Implementations

impl Clone for Range

fn clone(&self) -> Range

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Range

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Header for Range

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I: Iterator<Item = &'i HeaderValue>>( values: &mut I, ) -> Result<Self, Error>

Decode this type from an iterator of HeaderValues.

fn encode<E: Extend<HeaderValue>>(&self, values: &mut E)

Encode this type to a HeaderMap.

impl PartialEq for Range

fn eq(&self, other: &Range) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
