Struct sixtyfps_corelib::Callback[−][src]

#[repr(C)]
pub struct Callback<Arg: ?Sized, Ret = ()> { /* fields omitted */ }

A Callback that can be connected to a handler.

The Arg represents the argument. It should always be a tuple

Implementations

impl<Arg: ?Sized, Ret: Default> Callback<Arg, Ret>[src]

pub fn call(&self, a: &Arg) -> Ret[src]

Call the callback with the given argument.

pub fn set_handler(&self, f: impl Fn(&Arg) -> Ret + 'static)[src]

Set an handler to be called when the callback is called

There can only be one single handler per callback.
