Struct rustix::ioctl::patterns::IntegerSetter

pub struct IntegerSetter<Opcode> {
    value: usize,
    _opcode: PhantomData<Opcode>,
}

Implements an ioctl that passes an integer into the ioctl.

Fields

value: usize

The value to pass in.

_opcode: PhantomData<Opcode>

The opcode.

Implementations

impl<Opcode: CompileTimeOpcode> IntegerSetter<Opcode>

pub unsafe fn new(value: usize) -> Self

Create a new integer Ioctl helper.

Safety

• Opcode must provide a valid opcode.
• For this opcode, it must expect an integer.
• The integer is in the valid range for this opcode.

Trait Implementations

impl<Opcode: CompileTimeOpcode> Ioctl for IntegerSetter<Opcode>

type Output = ()

The type of the output data.

const IS_MUTATING: bool = false

Does the ioctl mutate any data in the userspace?

const OPCODE: Opcode = Opcode::OPCODE

The opcode used by this ioctl command.

fn as_ptr(&mut self) -> *mut c_void

Get a pointer to the data to be passed to the ioctl command.

unsafe fn output_from_ptr( _out: IoctlOutput, _extract_output: *mut c_void, ) -> Result<Self::Output>

Cast the output data to the correct type.
