Struct zi::Callback

pub struct Callback<InputT, OutputT = ()>(pub Rc<dyn Fn(InputT) -> OutputT>);

Callback wrapper. Useful for passing callbacks in child components Properties. An Rc wrapper is used to make it cloneable.

Implementations

impl<InputT, OutputT> Callback<InputT, OutputT>

pub fn emit(&self, value: InputT) -> OutputT

Trait Implementations

impl<InputT, OutputT> Clone for Callback<InputT, OutputT>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<InputT, OutputT, FnT> From<FnT> for Callback<InputT, OutputT> where
    FnT: Fn(InputT) -> OutputT + 'static, 

fn from(function: FnT) -> Self

Performs the conversion.

impl<InputT, OutputT> PartialEq<Callback<InputT, OutputT>> for Callback<InputT, OutputT>

fn eq(&self, _other: &Self) -> 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 !=.
