Enum capnp::OutputSegments

pub enum OutputSegments<'a> {
    SingleSegment([&'a [u8]; 1]),
    MultiSegment(Vec<&'a [u8]>),
}

Helper struct that allows MessageBuilder::get_segments_for_output() to avoid heap allocations in the single-segment case.

Variants

SingleSegment([&'a [u8]; 1])

MultiSegment(Vec<&'a [u8]>)

Trait Implementations

impl<'a> Deref for OutputSegments<'a>

type Target = [&'a [u8]]

The resulting type after dereferencing.

fn deref<'b>(&'b self) -> &'b [&'a [u8]]

Dereferences the value.

impl<'s> ReaderSegments for OutputSegments<'s>

fn get_segment<'a>(&'a self, id: u32) -> Option<&'a [u8]>

Gets the segment with index idx. Returns None if idx is out of range.

fn len(&self) -> usize

Gets the number of segments.
