Expand description

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
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.

Implementations

Returns true if this feature explicitly used dep: syntax.
