Struct headers::ContentRange

pub struct ContentRange { /* private fields */ }
Expand description

Content-Range, described in RFC7233

ABNF

Content-Range       = byte-content-range
                    / other-content-range

byte-content-range  = bytes-unit SP
                      ( byte-range-resp / unsatisfied-range )

byte-range-resp     = byte-range "/" ( complete-length / "*" )
byte-range          = first-byte-pos "-" last-byte-pos
unsatisfied-range   = "*/" complete-length

complete-length     = 1*DIGIT

other-content-range = other-range-unit SP other-range-resp
other-range-resp    = *CHAR

Example

use headers::ContentRange;

// 100 bytes (included byte 199), with a full length of 3,400
let cr = ContentRange::bytes(100..200, 3400).unwrap();

Implementations§

source§

impl ContentRange

source

pub fn bytes( range: impl RangeBounds<u64>, complete_length: impl Into<Option<u64>> ) -> Result<ContentRange, InvalidContentRange>

Construct a new Content-Range: bytes .. header.

source

pub fn unsatisfied_bytes(complete_length: u64) -> Self

Create a new ContentRange stating the range could not be satisfied.

The passed argument is the complete length of the entity.

source

pub fn bytes_range(&self) -> Option<(u64, u64)>

Get the byte range if satisified.

Note that these byte ranges are inclusive on both ends.

source

pub fn bytes_len(&self) -> Option<u64>

Get the bytes complete length if available.
