type Features

type Features int

Features is a set of flags reporting which features of generic Go code a package uses, or 0.

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

func ForPackage(inspect *inspector.Inspector, info *types.Info) Features

ForPackage computes which generic features are used directly by the package being analyzed.
