Actuate

Examples

A high-performance reactive user-interface framework for Rust. This crate provides a generic library that lets you define UI using declarative, type-safe syntax. Views combine together to form a statically-typed view tree that can be stored on the stack, giving this architecture its high performance.

struct Counter {
    initial: i32,
}

impl View for Counter {
    fn body(&self, cx: &Scope) -> impl View {
        let (count, set_count) = use_state(cx, || self.initial);

        (
            text(format!("High five count: {}", count)),
            div(text("Up high!")).on_click({
                clone!(count, set_count);
                move || set_count.set(count + 1)
            }),
            div(text("Down low!")).on_click({
                clone!(count);
                move || set_count.set(count - 1)
            }),
        )
    }
}

#[derive(Clone)]
struct App;

impl View for App {
    fn body(&self, _cx: &Scope) -> impl View {
        (Counter { initial: 0 }, Counter { initial: 100 })
    }
}

Inspiration

This crate is inspired by Xilem and uses a similar approach to type-safe reactivity. The main difference with this crate is the concept of scopes, components store their state in their own scope and updates to that scope re-render the component.

State management is inspired by React and Dioxus.
