Struct IntegerSetter

pub struct IntegerSetter<const OPCODE: Opcode> { /* private fields */ }

Implements an ioctl that passes an integer into the ioctl.

To compute a value for the OPCODE argument, see the functions in the opcode module.

Implementations

impl<const OPCODE: Opcode> IntegerSetter<OPCODE>

pub const unsafe fn new_usize(value: usize) -> Self

Create a new integer Ioctl helper containing a usize.

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.

pub const unsafe fn new_pointer(value: *mut c_void) -> Self

Create a new integer Ioctl helper containing a *mut c_void.

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<const OPCODE: Opcode> Ioctl for IntegerSetter<OPCODE>

const IS_MUTATING: bool = false

Does the ioctl mutate any data in the userspace?

type Output = ()

The type of the output data.

fn opcode(&self) -> Opcode

Get 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
