Struct AsyncifyFd 

pub struct AsyncifyFd<S, F, D> { /* private fields */ }

Spawn a blocking function with a file descriptor in the thread pool.

Implementations

impl<S, F, D> AsyncifyFd<S, F, D>

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

Create AsyncifyFd.

Trait Implementations

impl<S, F, D> IntoInner for AsyncifyFd<S, F, D>

type Inner = D

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<S, D, F> OpCode for AsyncifyFd<S, F, D>

where S: Sync, D: Send + 'static, F: FnOnce(&S) -> BufResult<usize, D> + Send + 'static,

Available on io_uring only.

type Control = ()

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

fn create_entry(&mut self, _control: &mut Self::Control) -> OpEntry

Create submission entry.

fn call_blocking(&mut self, _control: &mut Self::Control) -> Result<usize>

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

unsafe fn init(&mut self, _: &mut Self::Control)

Initialize the control

fn create_entry_fallback(&mut self, _: &mut Self::Control) -> OpEntry

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

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.

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

Push a multishot result to the inner queue.

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

Pop a multishot result from the inner queue.

impl<S, D, F> OpCode for AsyncifyFd<S, F, D>

where S: Sync, D: Send + 'static, F: FnOnce(&S) -> BufResult<usize, D> + Send + 'static,

Available on polling only.

type Control = ()

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

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

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

fn operate(&mut self, _: &mut Self::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 init(&mut self, _: &mut Self::Control)

Initialize the control

fn op_type(&mut self, _: &mut Self::Control) -> Option<OpType>

Get the operation type when an event is occurred.

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.
