pub enum FeaturesFor {
NormalOrDev,
HostDep,
ArtifactDep(CompileTarget),
}
Expand description
Flag to indicate if features are requested for a certain type of dependency.
This is primarily used for constructing a PackageFeaturesKey
to decouple
activated features of the same package with different types of dependency.
Variants§
NormalOrDev
Normal or dev dependency.
HostDep
Build dependency or proc-macro.
ArtifactDep(CompileTarget)
Any dependency with both artifact and target specified.
That is, dep = { …, artifact = <crate-type>, target = <triple> }
