Struct ByteRange 

#[non_exhaustive]
pub struct ByteRange {
    pub first: u64,
    pub last: Option<u64>,
}

A single byte range first-last (RFC 7233 2.1), inclusive.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

first: u64

First byte.

last: Option<u64>

Last byte; None for the open-ended form first-.

Implementations

impl ByteRange

pub fn new(first: u64, last: u64) -> Self

A closed range.

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

Number of bytes; None when open-ended or last < first.

pub fn is_empty(&self) -> bool

Whether the range is empty or open-ended (no byte count).

pub fn offset_len(&self) -> Result<(u64, u64), Unsupported>

The closed (offset, length) form, or the typed unsupported error for an open-ended range.

Errors

Unsupported::OpenEndedRange.
