Struct lde::OpCode

pub struct OpCode(_);

Byte slice representing an opcode.

Methods

impl OpCode

pub fn read<T: Int>(&self, offset: usize) -> T

Helps reading immediate and displacement values.

Examples

// mov eax, 0x01010101
let opcode: &lde::OpCode = b"\xB8\x01\x01\x01\x01".into();

// reads the immedate value
let result = opcode.read::<u32>(1);

assert_eq!(result, 0x01010101);

Panics

Panics if offset..offset + sizeof(T) is out of bounds.

pub fn write<T: Int>(&mut self, offset: usize, val: T) -> &mut OpCode

Helps writing immediate and displacement values.

Examples

// mov al, 1
let mut opcode = [0xb0, 0x01];
let opcode: &mut lde::OpCode = (&mut opcode).into();

// change the immediate to 0xff
opcode.write(1, 0xff_u8);

assert_eq!(opcode, &[0xb0, 0xff]);

Panics

Panics if offset..offset + sizeof(T) is out of bounds.

Trait Implementations

impl Eq for OpCode
