Enum cargo::core::summary::FeatureValue

source ·

pub enum FeatureValue {
    Feature(InternedString),
    Crate(InternedString),
    CrateFeature(InternedString, InternedString),
}

Expand description

FeatureValue represents the types of dependencies a feature can have:

Another feature
An optional dependency
A feature in a dependency

The selection between these 3 things happens as part of the construction of the FeatureValue.

Variants

Feature(InternedString)

Crate(InternedString)
