Features is a set of flags reporting which features of generic Go code a package uses, or 0.
type Features int
const (
// GenericTypeDecls indicates whether the package declares types with type
// parameters.
GenericTypeDecls Features = 1 << iota
// GenericFuncDecls indicates whether the package declares functions with
// type parameters.
GenericFuncDecls
// EmbeddedTypeSets indicates whether the package declares interfaces that
// contain structural type restrictions, i.e. are not fully described by
// their method sets.
EmbeddedTypeSets
// TypeInstantiation indicates whether the package instantiates any generic
// types.
TypeInstantiation
// FuncInstantiation indicates whether the package instantiates any generic
// functions.
FuncInstantiation

func ForPackage(inspect *inspector.Inspector, info *types.Info) Features
ForPackage computes which generic features are used directly by the package being analyzed.
