Struct FileStat

pub struct FileStat<S>
where
    S: AsRawFd,
{ /* private fields */ }

A fused FileStat operation

Implementations

impl<S> FileStat<S>

where S: AsRawFd,

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

Create a new FileStat.

Trait Implementations

impl<S> IntoInner for FileStat<S>

where S: AsRawFd,

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

The inner type.

fn into_inner(self) -> <FileStat<S> as IntoInner>::Inner

Get the inner buffer.

impl<S> OpCode for FileStat<S>

where S: AsRawFd,

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

Create submission entry.

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

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.

impl<S> OpCode for FileStat<S>

where S: AsRawFd,

fn pre_submit(self: Pin<&mut FileStat<S>>) -> Result<Decision, Error>

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

fn op_type(self: Pin<&mut FileStat<S>>) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate(self: Pin<&mut FileStat<S>>) -> Poll<Result<usize, Error>>

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