You need to either use `edition = "2021"`, or set `resolver = "2"` in the `[workspace`] section of your to-level `Cargo.toml`. See [this link](https://doc.rust-lang.org/edition-guide/rust-2021/default-cargo-resolver.html) for more info.
|
||||
|
||||
You can opt-in to the using [`egui_wgpu`](https://github.com/emilk/egui/tree/master/egui_wgpu) for rendering by enabling the `wgpu` feature and setting `NativeOptions::renderer` to `Renderer::Wgpu`.
|
||||
|
||||
|
||||
## Alternatives
|
||||
`eframe` is not the only way to write an app using `egui`! You can also try [`egui-miniquad`](https://github.com/not-fl3/egui-miniquad), [`bevy_egui`](https://github.com/mvlabat/bevy_egui), [`egui_sdl2_gl`](https://github.com/ArjunNair/egui_sdl2_gl), and others.
