[−][src]Struct cursive::event::Callback
Callback is a function that can be triggered by an event. It has a mutable access to the cursive root.
It is meant to be stored in views.
Implementations
impl Callback
[src]
pub fn from_fn<F>(f: F) -> Callback where
F: 'static + Fn(&mut Cursive),
[src]
F: 'static + Fn(&mut Cursive),
Wraps the given function into a Callback
object.
pub fn from_fn_mut<F>(f: F) -> Callback where
F: 'static + FnMut(&mut Cursive),
[src]
F: 'static + FnMut(&mut Cursive),
Wrap a FnMut
into a Callback
object.
If this methods tries to call itself, nested calls will be no-ops.
pub fn dummy() -> Callback
[src]
Returns a dummy callback that doesn't run anything.
