Struct PathStat 

pub struct PathStat<S: AsFd> { /* private fields */ }

A fused PathStat operation

Implementations

impl<S: AsFd> PathStat<S>

pub fn new(dirfd: S, path: CString, follow_symlink: bool) -> Self

Create a new PathStat.

Trait Implementations

impl<S: AsFd> IntoInner for PathStat<S>

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

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<S: AsFd> OpCode for PathStat<S>

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

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

unsafe fn init(&mut self, ctrl: &mut <Self as PollOpCode>::Control)

Initialize the control

fn pre_submit( &mut self, control: &mut <Self as PollOpCode>::Control, ) -> Result<Decision>

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 <Self as PollOpCode>::Control, ) -> Option<OpType>

Get the operation type when an event is occurred.

fn operate( &mut self, control: &mut <Self as PollOpCode>::Control, ) -> Poll<Result<usize>>

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>, _: &Extra, )

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

impl<S: AsFd> OpCode for PathStat<S>

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

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

unsafe fn init(&mut self, ctrl: &mut <Self as IourOpCode>::Control)

Initialize the control

fn create_entry( &mut self, control: &mut <Self as IourOpCode>::Control, ) -> OpEntry

Create submission entry.

fn create_entry_fallback( &mut self, control: &mut <Self as IourOpCode>::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 <Self as IourOpCode>::Control, ) -> Result<usize>

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

unsafe fn set_result( &mut self, control: &mut <Self as IourOpCode>::Control, result: &Result<usize>, 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 <Self as IourOpCode>::Control, result: Result<usize>, extra: Extra, )

Push a multishot result to the inner queue.

fn pop_multishot( &mut self, control: &mut <Self as IourOpCode>::Control, ) -> Option<BufResult<usize, Extra>>

Pop a multishot result from the inner queue.
