Trait Implementations

impl Architecture for X86

const JMP_REL_SIZE: usize = 5usize

size of a near relative jump instruction (jmp rel32)

const JMP_ABS_SIZE: usize = 6usize

size of an absolute jump stub (varies by architecture)

const PTR_SIZE: usize = 4usize

native pointer size in bytes

const CODE_ALIGNMENT: usize = 4usize

required alignment for executable code

const MIN_HOOK_SIZE: usize = 5usize

minimum bytes needed to install a hook typically JMP_REL_SIZE for near targets, JMP_ABS_SIZE for far

fn encode_jmp_rel(source: usize, target: usize) -> Option<Vec<u8>>

encode a near relative jump from source to target

fn encode_jmp_abs(target: usize) -> Vec<u8>

encode an absolute jump (architecture-specific stub)

fn encode_call_rel(source: usize, target: usize) -> Option<Vec<u8>>

encode a relative call instruction

fn encode_nop_sled(size: usize) -> Vec<u8>

encode a NOP sled of the specified size

fn find_instruction_boundary(code: &[u8], required_size: usize) -> Option<usize>

find instruction boundary at or after required_size bytes

fn relocate_instruction( instruction: &[u8], old_address: usize, new_address: usize, ) -> Option<Vec<u8>>

relocate an instruction that was moved to a new address

fn needs_relocation(instruction: &[u8]) -> bool

check if an instruction needs relocation when moved

fn preferred_hook_size(target: usize, detour: usize) -> usize

preferred hook method based on distance between target and detour
