Struct DeviceIoControl 

pub struct DeviceIoControl<S, I: IoBuf, O: IoBufMut> { /* private fields */ }

Available on Windows only.

Send a control code to a device.

Implementations

impl<S, I: IoBuf, O: IoBufMut> DeviceIoControl<S, I, O>

pub fn new( fd: S, ioctl_code: u32, input_buffer: Option<I>, output_buffer: Option<O>, ) -> Self

Create DeviceIoControl.

Trait Implementations

impl<S, I: IoBuf, O: IoBufMut> IntoInner for DeviceIoControl<S, I, O>

type Inner = (Option<I>, Option<O>)

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<S: AsFd, I: IoBuf, O: IoBufMut> OpCode for DeviceIoControl<S, I, O>

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.
