Cargo Features

[dependencies]
file-lfu = { version = "1.4.1", default-features = false, features = ["utf8-paths", "uuid-as-key"] }
default = uuid-as-key

The uuid-as-key feature is set by default whenever file-lfu is added without default-features = false somewhere in the dependency tree.

utf8-paths = camino
uuid-as-key default = uuid

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.

camino utf8-paths?
uuid uuid-as-key
