Trait dioxus::prelude::Dependency

pub trait Dependency: Sized + Clone {
    type Out: Clone + PartialEq + 'static;

Available on crate feature hooks only.

A dependency is a trait that can be used to determine if a effect or selector should be re-run.

Required Associated Types

type Out: Clone + PartialEq + 'static

The output of the dependency

Required Methods

fn out(&self) -> Self::Out

Returns the output of the dependency.

Provided Methods

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

Returns true if the dependency has changed.

Object Safety

This trait is not object safe.
