Struct Splice 

pub struct Splice<S1, S2> { /* private fields */ }

Available on linux_all only.

Splice data between two file descriptors.

Implementations

impl<S1, S2> Splice<S1, S2>

pub fn new( fd_in: S1, offset_in: i64, fd_out: S2, offset_out: i64, len: usize, flags: u32, ) -> Self

Available on Unix only.

Create Splice.

offset_in and offset_out specify the offset to read from and write to. Use -1 for pipe ends or to use/update the current file position.

Trait Implementations

impl<S1: AsFd, S2: AsFd> OpCode for Splice<S1, S2>

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 op_type(self: Pin<&mut Self>) -> Option<OpType>

Get the operation type when an event is occurred.

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

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

impl<S1: AsFd, S2: AsFd> OpCode for Splice<S1, S2>

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.

unsafe fn set_result(self: Pin<&mut Self>, _: usize)

Set the result when it successfully completes. The operation stores the result and is responsible to release it if the operation is cancelled.
