Overview

is a cross-platform GUI library for Rust. It aims to be extremely performant while providing world-class developer ergonomics.

Supporting both GPU and CPU rendering, Floem gives you performance that's closest to bare metal. Also primitives are provided to help the developer to write performant UI code without too much effect.

use floem::{
    reactive::create_signal,
    views::{button, label, Decorators},
    IntoView,
};

fn app_view() -> impl IntoView {
    // Create a reactive signal with a counter value, defaulting to 0
    let (counter, mut set_counter) = create_signal(0);

    // Create a vertical layout
    (
        // The counter value updates automatically, thanks to reactivity
        label(move || format!("Value: {counter}")),
        // Create a horizontal layout
        (
            button("Increment").action(move || set_counter += 1),
            button("Decrement").action(move || set_counter -= 1),
        ),
    ).style(|s| s.flex_col())
}

fn main() {
    floem::launch(app_view);
}

Features

Customisable widgets: Don't want the default look? You can change pretty much anything you want using the styling API, or install a third-party theme.
