Cargo Features

[dependencies]
main_loop = { version = "0.3.3", default-features = false, features = ["glutin", "winit"] }
default = glutin, winit

These default features are set whenever main_loop is added without default-features = false somewhere in the dependency tree.

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

glutin default

Affects main_loop::glutin

winit default

Affects main_loop::winit
