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.

It is meant to be stored in views.

Implementations

impl Callback

pub fn from_fn<F>(f: F) -> Callback where
    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), 

Wrap a FnMut into a Callback object.

If this methods tries to call itself, nested calls will be no-ops.

pub fn from_fn_once<F>(f: F) -> Callback where
    F: 'static + FnOnce(&mut Cursive), 

Wrap a FnOnce into a Callback object.

After being called once, the callback will become a no-op.

pub fn dummy() -> Callback

Returns a dummy callback that doesn’t run anything.

Trait Implementations

impl Clone for Callback

pub fn clone(&self) -> Callback

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Deref for Callback

type Target = dyn Fn(&mut Cursive) + 'static

The resulting type after dereferencing.

pub fn deref(&self) -> &<Callback as Deref>::Target

Dereferences the value.

impl From<Box<dyn Fn(&mut Cursive) + 'static, Global>> for Callback

pub fn from(f: Box<dyn Fn(&mut Cursive) + 'static, Global>) -> Callback

Performs the conversion.

impl From<Rc<dyn Fn(&mut Cursive) + 'static>> for Callback

pub fn from(f: Rc<dyn Fn(&mut Cursive) + 'static>) -> Callback

Performs the conversion.
