Types

type Features

type Features = genericfeatures.Features

type Result

type Result struct {
	Direct, Transitive Features
}

Result is the usesgenerics analyzer result type. The Direct field records features used directly by the package being analyzed (i.e. contained in the package source code). The Transitive field records any features used by the package or any of its transitive imports.
