Cargo Features

[dependencies]
zapper = { version = "0.9.1", default-features = false, features = ["derive", "rayon"] }
default = derive, rayon

These default features are set whenever zapper is added without default-features = false somewhere in the dependency tree.

derive default = zapper_derive

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.
