Struct IoctlReqWriteVal

pub struct IoctlReqWriteVal<Device: IoDevice, Arg, Result = int>
where
    Arg: AsRawV,
{ /* private fields */ }

Implementation of IoctlReq with a fixed cmd value and passing a direct value from memory, without pointer indirection.

Trait Implementations

impl<Device: IoDevice, Arg: AsRawV, Result> Clone for IoctlReqWriteVal<Device, Arg, Result>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, Device, Arg, Result> IoctlReq<'a, Device> for IoctlReqWriteVal<Device, Arg, Result>

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

type ExtArg = Arg

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 = Arg

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, arg: &Self::ExtArg, _: &mut MaybeUninit<Self::TempMem>, ) -> (ulong, Arg)

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

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

Prepare a raw successful result from a ioctl call to be returned.
