Struct freya::prelude::UseCallback

pub struct UseCallback<T, O>
where
    T: 'static,
    O: 'static + ?Sized,
{ /* private fields */ }

This callback is not generic over a return type so you can hold a bunch of callbacks at once

If you need a callback that returns a value, you can simply wrap the closure you pass in that sets a value in its scope

Implementations

impl<T, O> UseCallback<T, O>

pub fn call(&self, value: T) -> O

Call the callback

Trait Implementations

impl<T, O> Clone for UseCallback<T, O>

where T: 'static, O: 'static + ?Sized,

fn clone(&self) -> UseCallback<T, O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, O> Debug for UseCallback<T, O>

where T: 'static, O: 'static + ?Sized,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T, O> Deref for UseCallback<T, O>

type Target = dyn Fn(T) -> O

The resulting type after dereferencing.

fn deref(&self) -> &<UseCallback<T, O> as Deref>::Target

Dereferences the value.

impl<T, O> PartialEq for UseCallback<T, O>

where T: 'static, O: 'static + ?Sized,

fn eq(&self, other: &UseCallback<T, O>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T, O> Copy for UseCallback<T, O>

where T: 'static, O: 'static,
