Cargo Features

[dependencies]
happylock = { version = "0.3.0", default-features = false, features = ["spin", "parking_lot"] }

default = parking_lot

The parking_lot feature is set by default whenever happylock 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.
