Functions

func Enabled

func Enabled() bool

Enabled reports whether NewAlias should create types.Alias types.

This function is expensive! Call it sparingly.

func NewAlias

func NewAlias(enabled bool, pos token.Pos, pkg *types.Package, name string, rhs types.Type) *types.TypeName

NewAlias creates a new TypeName in Package pkg that is an alias for the type rhs.

The enabled parameter determines whether the resulting [TypeName]'s type is an types.Alias. Its value must be the result of a call to Enabled, which computes the effective value of GODEBUG=gotypesalias=... by invoking the type checker. The Enabled function is expensive and should be called once per task (e.g. package import), not once per call to NewAlias.

func Rhs

func Rhs(alias *Alias) types.Type

Rhs returns the type on the right-hand side of the alias declaration.

func Unalias

func Unalias(t types.Type) types.Type

Unalias is a wrapper of types.Unalias.

Types

type Alias

type Alias = types.Alias

Alias is an alias of types.Alias.
