Cargo Features

[dependencies]
zxcvbn = { version = "2.2.2", default-features = false, features = ["ser", "builder"] }
default = builder

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

ser = serde, serde_derive
builder default = derive_builder

Features from optional dependencies

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