Cargo Features

[dependencies]
uinput = { version = "0.1.3", default-features = false, features = ["udev"] }
default = udev

The udev feature is set by default whenever uinput is added without default-features = false somewhere in the dependency tree.

udev default = libudev

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.
