A fused FileStat operation

Implementations

impl<S: AsRawFd> FileStat<S>

pub fn new(fd: SharedFd<S>) -> Self

Create a new FileStat.

Trait Implementations

impl<S: AsRawFd> IntoInner for FileStat<S>

type Inner = <FileStat<S> as IntoInner>::Inner

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<S: AsRawFd> OpCode for FileStat<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 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<S: AsRawFd> OpCode for FileStat<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.

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.
