Struct IoctlReqConstArg

pub struct IoctlReqConstArg<Device: IoDevice, Result, const ARG: int> { /* private fields */ }

Implementation of IoctlReq with a fixed cmd and passing a constant int as the argument, then returning the kernel’s result value.

Trait Implementations

impl<Device: IoDevice, Result, const ARG: int> Clone for IoctlReqConstArg<Device, Result, ARG>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, Device, Result, const ARG: int> IoctlReq<'a, Device> for IoctlReqConstArg<Device, Result, ARG>

where Result: 'a + FromIoctlResult<int>, Device: 'a + IoDevice,

type ExtArg = ()

The type that the caller will provide when using this ioctl command.

type TempMem = ()

The type of some temporary memory that the request needs to do its work.

type RawArg = i32

The type of argument that will be passed to the raw system call.

type Result = Result

The type of the result of the fcntl call.

fn prepare_ioctl_args( &self, _: &Self::ExtArg, _: &mut MaybeUninit<Self::TempMem>, ) -> (ulong, Self::RawArg)

Prepare the cmd and arg values for a ioctl system call.

fn prepare_ioctl_result( &self, raw: int, _: &Self::ExtArg, _: &MaybeUninit<Self::TempMem>, ) -> Self::Result
