Enum ByteRange 

pub enum ByteRange {
    Full,
    Part(u64, u64),
    Unsatisfiable,
}

What a Range header asks for, for a body of a known length.

Variants

Full

No range, another unit or several ranges: the whole body with 200.

Part(u64, u64)

First and last byte, inclusive: 206.

Unsatisfiable

A bytes range that is malformed or starts past the end: 416.

Implementations

impl ByteRange

pub fn parse(header: Option<&str>, len: u64) -> ByteRange

Reads a single bytes= range: a-b, a- or the suffix -n.

use zeyn::ByteRange;
assert_eq!(ByteRange::parse(Some("bytes=0-99"), 1000), ByteRange::Part(0, 99));
assert_eq!(ByteRange::parse(Some("bytes=-500"), 1000), ByteRange::Part(500, 999));
assert_eq!(ByteRange::parse(Some("bytes=900-"), 1000), ByteRange::Part(900, 999));
assert_eq!(ByteRange::parse(Some("bytes=0-5000"), 1000), ByteRange::Part(0, 999));
assert_eq!(ByteRange::parse(Some("bytes=1000-"), 1000), ByteRange::Unsatisfiable);
assert_eq!(ByteRange::parse(Some("bytes=5-1"), 1000), ByteRange::Unsatisfiable);
assert_eq!(ByteRange::parse(Some("bytes=0-1,5-6"), 1000), ByteRange::Full);
assert_eq!(ByteRange::parse(None, 1000), ByteRange::Full);
