Cargo Features

depcycle-y has no features set by default.

[dependencies]
depcycle-y = { version = "1.0.0", features = ["x"] }
x = depcycle-x

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.
