Cargo Features

[dependencies]
serialport5 = { version = "5.0.2", default-features = false, features = ["libudev"] }
default = libudev

The libudev feature is set by default whenever serialport5 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.
