Cargo Features

[dependencies]
negatable-set = { version = "0.1.0", default-features = false, features = ["vc", "serde"] }
default = serde

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

vc = smallvec, vec-collections

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.
