Struct HotPatchHook 

pub struct HotPatchHook<A: Architecture> { /* private fields */ }

hot-patch style hook

uses the mov edi, edi / padding space present in Windows hot-patchable functions. only modifies 2 bytes at the function entry point atomically.

Implementations

impl<A: Architecture> HotPatchHook<A>

pub fn new(target: usize, detour: usize) -> Self

create a new hot-patch hook

pub fn is_patchable(target: usize) -> bool

check if the target function is hot-patchable

looks for:

• 5 bytes of padding (CC or 90) at target-5
• 2-byte NOP (8B FF = mov edi,edi or 66 90) at target

pub fn install(self) -> Result<HookGuard<A>>

install the hot-patch hook

Trait Implementations

fn install(self) -> Result<Self::Guard>

install the hook

fn target(&self) -> usize

get the target address

fn detour(&self) -> usize
