Struct detour::RawDetour [−][src]
pub struct RawDetour(_);
Expand description
A raw detour.
Example
use detour::RawDetour; use std::mem; fn add5(val: i32) -> i32 { val + 5 } fn add10(val: i32) -> i32 { val + 10 } let mut hook = unsafe { RawDetour::new(add5 as *const (), add10 as *const ())? }; assert_eq!(add5(5), 10); assert_eq!(hook.is_enabled(), false); unsafe { hook.enable()? }; assert!(hook.is_enabled()); let original: fn(i32) -> i32 = unsafe { mem::transmute(hook.trampoline()) }; assert_eq!(add5(5), 15); assert_eq!(original(5), 10); unsafe { hook.disable()? }; assert_eq!(add5(5), 10);
Implementations
Constructs a new inline detour patcher.
The hook is disabled by default. Even when this function is succesful, there is no guaranteee that the detour function will actually get called when the target function gets called. An invocation of the target function might for example get inlined in which case it is impossible to hook at runtime.
Returns whether the detour is enabled or not.
Returns a reference to the generated trampoline.
