### What From the [lint description](https://rust-lang.github.io/rust-clippy/master/index.html?search=or_fu#or_fun_call): > The function will always be called. This is only bad if it allocates or does some non-trivial amount of work. But also: > If the function has side-effects, not calling it will change the semantic of the program, but you shouldn’t rely on that. > > The lint also cannot figure out whether the function you call is actually expensive to call or not. Still worth it to keep our happy paths clean, imo.
egui_extras
This is a crate that adds some features on top top of egui. This crate is for experimental features, and features that require big dependencies that do not belong in egui.
Images
One thing egui_extras is commonly used for is to install image loaders for egui:
egui_extras = { version = "*", features = ["all_loaders"] }
image = { version = "0.25", features = ["jpeg", "png"] } # Add the types you want support for
egui_extras::install_image_loaders(egui_ctx);
