Overview

Show `puffin` profiler flamegraph in-game using `egui`

puffin is an instrumentation profiler where you opt-in to profile parts of your code:

fn my_function() {
    puffin::profile_function!();
    if ... {
        puffin::profile_scope!("load_image", image_name);
        ...
    }
}

puffin_egui allows you to inspect the resulting profile data using egui, and immediate mode GUI library, using only one line of code:

puffin_egui::profiler_window(egui_ctx);

See the examples/ folder for how to use it with eframe or macroquad.

To try it out, run cargo run --release --example macroquad

Option to sort threads by name

There's an attempt at using puffin_egui in bevy, and currently the compute threads are a bit out-of-order. I suspect one solution would be to provide an option to sort the streams here: https://github.com/emilk/puffin_egui/blob/ba608f9d2fa20c89317fd3990491a103c0c88771/src/lib.rs#L327
