Struct cursive::event::Callback

pub struct Callback(_);

Callback is a function that can be triggered by an event. It has a mutable access to the cursive root.

Methods

impl Callback

pub fn from_fn<F>(f: F) -> Self where
    F: 'static + Fn(&mut Cursive), 

Wraps the given function into a Callback object.

pub fn from_fn_mut<F>(f: F) -> Self where
    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() -> Self

Returns a dummy callback that doesn't run anything.
