Struct Callback 

pub struct Callback<T: 'static> { /* private fields */ }

A type-erased, cloneable callback.

Used by components to accept event handler functions from consumers without coupling to a specific framework’s callback type.

Framework adapters convert framework-specific callbacks (e.g., Leptos Callback, Dioxus closures) to and from this type.

Implementations

impl<T: 'static> Callback<T>

pub fn new(f: impl Fn(T) + Send + Sync + 'static) -> Self

Create a new callback from a function.

pub fn call(&self, arg: T)

Invoke the callback with the given argument.

Trait Implementations

impl<T: 'static> Clone for Callback<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: 'static> Debug for Callback<T>

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

Formats the value using the given formatter.

impl<T: 'static> PartialEq for Callback<T>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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