FeatureValue represents the types of dependencies a feature can have.

Variants

Feature(InternedString)

A feature enabling another feature.

Dep

Fields

dep_name: InternedString

A feature enabling a dependency with dep:dep_name syntax.

DepFeature

Fields

dep_name: InternedString

dep_feature: InternedString

dep_prefix: bool

If this is true, then the feature used the dep: prefix, which prevents enabling the feature named dep_name.

weak: bool

If true, indicates the ? syntax is used, which means this will not automatically enable the dependency unless the dependency is activated through some other means.

A feature enabling a feature on a dependency with crate_name/feat_name syntax.
