Struct capnp::serialize::BufferSegments

pub struct BufferSegments<T> { /* private fields */ }

Segments read from a buffer, useful for when you have the message in a buffer and don’t want the extra copy of read_message.

Implementations

impl<T: Deref<Target = [u8]>> BufferSegments<T>

pub fn new(buffer: T, options: ReaderOptions) -> Result<BufferSegments<T>>

Reads a serialized message (including a segment table) from a buffer and takes ownership, without copying. The buffer is allowed to be longer than the message. Provide this to Reader::new with options that make sense for your use case. Very long lived mmaps may need unlimited traversal limit.

ALIGNMENT: If the “unaligned” feature is enabled, then there are no alignment requirements on buffer. Otherwise, buffer must be 8-byte aligned (attempts to read the message will trigger errors).

pub fn into_buffer(self) -> T

Trait Implementations

impl<T: Deref<Target = [u8]>> ReaderSegments for BufferSegments<T>

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

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

fn len(&self) -> usize

Gets the number of segments.
