Struct IntegerSetter

Source 
pub struct IntegerSetter<Opcode> { /* private fields */ }
Expand description

Implements an ioctl that passes an integer into the ioctl.

Implementations§

Source§

impl<Opcode: CompileTimeOpcode> IntegerSetter<Opcode>

Source

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.
