Trait ProcBoolMethodExt 

Source 
pub trait ProcBoolMethodExt: Sized {
    // Required method
    fn from_fn<T: IProcInst>(
        target: T,
        callback: extern "C" fn(T, OptionalMethod) -> bool,
    ) -> Option<Self>;
}

Required Methods§

Source

fn from_fn<T: IProcInst>( target: T, callback: extern "C" fn(T, OptionalMethod) -> bool, ) -> Option<Self>

Bind target and call callback on it (returning bool). Like ProcVoidMethod, Invoke() takes no VM argument, so the bound target is the only object the callback sees. The callback’s first parameter is forced to the same type as target.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
