Struct sauron::Callback

pub struct Callback<IN, OUT>(_);

A generic sized representation of a function that can be attached to a Node. The callback will essentially be owned by the element

Methods

impl<IN, OUT> Callback<IN, OUT> where
    IN: 'static,
    OUT: 'static, 

pub fn emit<T>(&self, value: T) -> OUT where
    T: Into<IN>, 

This method calls the actual callback.

pub fn reform<F, IN2>(self, func: F) -> Callback<IN2, OUT> where
    F: Fn(IN2) -> IN + 'static, 

Changes input type of the callback to another. Works like common map method but in an opposite direction.

pub fn map<F, OUT2>(self, func: F) -> Callback<IN, OUT2> where
    F: Fn(OUT) -> OUT2 + 'static, 

Map the output of this callback to return a different type

Trait Implementations

impl<IN, OUT> Clone for Callback<IN, OUT> where
    IN: Clone,
    OUT: Clone, 

fn clone(&self) -> Callback<IN, OUT>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<IN, OUT> Debug for Callback<IN, OUT>

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

Formats the value using the given formatter.

impl<IN, OUT> PartialEq<Callback<IN, OUT>> for Callback<IN, OUT>

fn eq(&self, rhs: &Callback<IN, OUT>) -> bool

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

#[must_use]

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

This method tests for !=.

impl<IN, F, OUT> From<F> for Callback<IN, OUT> where
    F: Fn(IN) -> OUT + 'static, 

fn from(func: F) -> Callback<IN, OUT>

Performs the conversion.
