Struct FileStat 

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

A fused FileStat operation

Implementations

impl<S> FileStat<S>

where S: AsFd,

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

Create a new FileStat.

Trait Implementations

impl<S> IntoInner for FileStat<S>

where S: AsFd,

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: AsFd,

type Control = <FileStat<S> as OpCode>::Control

Type that contains self-references and other needed info during the operation

unsafe fn init(&mut self, ctrl: &mut <FileStat<S> as OpCode>::Control)

Initialize the control

fn create_entry( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> OpEntry

Create submission entry.

fn create_entry_fallback( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> OpEntry

Create submission entry for fallback. This method will only be called if create_entry returns an entry with unsupported opcode.

fn call_blocking( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> Result<usize, Error>

Call the operation in a blocking way. This method will be called if

unsafe fn set_result( &mut self, control: &mut <FileStat<S> as OpCode>::Control, result: &Result<usize, Error>, extra: &Extra, )

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

unsafe fn push_multishot( &mut self, control: &mut <FileStat<S> as OpCode>::Control, result: Result<usize, Error>, extra: Extra, )

Push a multishot result to the inner queue.

fn pop_multishot( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> Option<BufResult<usize, Extra>>

Pop a multishot result from the inner queue.

impl<S> OpCode for FileStat<S>

where S: AsFd,

type Control = <FileStat<S> as OpCode>::Control

Type that contains self-references and other needed info during the operation

unsafe fn init(&mut self, ctrl: &mut <FileStat<S> as OpCode>::Control)

Initialize the control

fn pre_submit( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> Result<Decision, Error>

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

fn op_type( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate( &mut self, control: &mut <FileStat<S> as OpCode>::Control, ) -> Poll<Result<usize, Error>>

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

unsafe fn set_result( &mut self, _: &mut Self::Control, _: &Result<usize, Error>, _: &Extra, )

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