Cargo Features

[dependencies]
tower-cache = { version = "0.0.1", default-features = false, features = ["lru"] }
default = lru

The lru feature is set by default whenever tower-cache 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.
