Struct fui_core::Callback

pub struct Callback<A> { /* fields omitted */ }

Callback can hold one listener that can be queued to execute with emit() method. The real execution will be done later on the same thread (you must explicitly call CallbackExecutor::execute_all_in_queue() to do it). Callbacks are queued because this prevents mutability problems when callbacks are called from callbacks.

Callback is the owner of the listener clousure.
