Cargo Features

memoize = { version = "0.4.2", default-features = false, features = ["full"] }
default = full

The full feature is set by default whenever memoize is added without default-features = false somewhere in the dependency tree.

full default = lru

Enables full of memoize-inner

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
