Cargo Features

pixel_formats = { version = "0.1.5", default-features = false, features = ["bitfrob", "bytemuck"] }
default = bitfrob, bytemuck

These default features are set whenever pixel_formats 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.
