Struct ReadManaged 

pub struct ReadManaged<S> { /* private fields */ }

Read a file into managed buffer.

Implementations

impl<S> ReadManaged<S>

pub fn new( fd: S, pool: &BufferPool, len: usize, ) -> Result<ReadManaged<S>, Error>

Create ReadManaged.

Trait Implementations

impl<S> OpCode for ReadManaged<S>

where S: AsFd,

type Control = ()

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

unsafe fn operate( &mut self, control: &mut (), optr: *mut OVERLAPPED, ) -> Poll<Result<usize, Error>>

Perform Windows API call with given pointer to overlapped struct.

fn cancel( &mut self, control: &mut (), optr: *mut OVERLAPPED, ) -> Result<(), Error>

Cancel the async IO operation.

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

Initialize the control

fn op_type(&self, control: &Self::Control) -> OpType

Determines that the operation is really overlapped defined by Windows API. If not, the driver will try to operate it in another thread.

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.

impl<S> TakeBuffer for ReadManaged<S>

type Buffer = BufferRef

Type of the buffer.

fn take_buffer(self) -> Option<BufferRef>

Take buffer.
