pub enum FeatureKind {
Base,
Named,
OptionalDependency,
}
Expand description
The kind of a particular feature within a package.
Returned by FeatureMetadata
.
Variants§
Base
The “base” feature. Every package has one such feature.
Named
This is a named feature in the [features]
section, or an implicit feature that corresponds to
an optional dependency.
For versions of Cargo prior to 1.60, optional dependencies always create implicit features by the same name. For versions 1.60 and greater, optional dependencies may create implicit features if the dependency doesn’t exist with the name “dep” in it.
OptionalDependency
This is an optional dependency.
