Struct RecvChain 

pub struct RecvChain { /* private fields */ }

Payload received from the producer, safely copied out of shared memory.

Created by VirtqConsumer::poll. Device-readable segments are eagerly copied during poll using MemOps::read (volatile on the host side), so accessing data requires no unsafe code and no references into shared memory. Segment boundaries are preserved in Segments.

Implementations

impl RecvChain

pub fn token(&self) -> Token

The token identifying this chain.

pub fn segments(&self) -> &Segments

The chain payload as ordered byte segments.

pub fn into_segments(self) -> Segments

Consume the chain, taking ownership of the segments.

pub fn to_bytes(&self) -> Bytes

Return the chain payload as contiguous bytes.

Returns empty Bytes when the chain has no readable buffers.

pub fn into_bytes(self) -> Bytes

Consume the chain and return the payload as contiguous bytes.
