Expand description
FeatureValue represents the types of dependencies a feature can have.
Variants§
Feature(InternedString)
A feature enabling another feature.
Dep
A feature enabling a dependency with dep:dep_name
syntax.
Fields
§
dep_name: InternedString
DepFeature
A feature enabling a feature on a dependency with crate_name/feat_name
syntax.
