Cargo Features

[dependencies]
spelling = { version = "0.2.4", default-features = false, features = ["use_rayon"] }
default = use_rayon

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

use_rayon default = rayon

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.
