Struct RecvMsg

pub struct RecvMsg<T: IoVectoredBufMut, C: IoBufMut, S> { /* private fields */ }

Receive data and source address with ancillary data into vectored buffer.

Implementations

impl<T: IoVectoredBufMut, C: IoBufMut, S> RecvMsg<T, C, S>

pub fn new(fd: SharedFd<S>, buffer: T, control: C) -> Self

Create RecvMsg.

Panics

This function will panic if the control message buffer is misaligned.

Trait Implementations

impl<T: IoVectoredBufMut, C: IoBufMut, S> IntoInner for RecvMsg<T, C, S>

type Inner = ((T, C), sockaddr_storage, u32, usize)

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<T: IoVectoredBufMut, C: IoBufMut, S: AsRawFd> OpCode for RecvMsg<T, C, S>

fn pre_submit(self: Pin<&mut Self>) -> Result<Decision>

Perform the operation before submit, and return Decision to indicate whether submitting the operation to polling is required.

fn on_event(self: Pin<&mut Self>, event: &Event) -> Poll<Result<usize>>

Perform the operation after received corresponding event. If this operation is blocking, the return value should be Poll::Ready.

impl<T: IoVectoredBufMut, C: IoBufMut, S: AsRawFd> OpCode for RecvMsg<T, C, S>

fn create_entry(self: Pin<&mut Self>) -> OpEntry

Create submission entry.

fn call_blocking(self: Pin<&mut Self>) -> Result<usize>

Call the operation in a blocking way. This method will only be called if [create_entry] returns OpEntry::Blocking.
