Implementations

impl<T: IoBuf, S> WriteAt<T, S>

pub fn new(fd: SharedFd<S>, offset: u64, buffer: T) -> Self

Create WriteAt.

Trait Implementations

impl<T: Debug + IoBuf, S: Debug> Debug for WriteAt<T, S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: IoBuf, S> IntoInner for WriteAt<T, S>

type Inner = T

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<T: IoBuf, S: AsRawFd> OpCode for WriteAt<T, S>

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

Perform Windows API call with given pointer to overlapped struct.

unsafe fn cancel(self: Pin<&mut Self>, optr: *mut OVERLAPPED) -> Result<()>

Cancel the async IO operation.

fn op_type(&self) -> OpType

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