Functions
Enabled function #
Enabled reports whether [NewAlias] should create [types.Alias] types. This function is expensive! Call it sparingly.
func Enabled() boolNewAlias function #
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. Precondition: enabled || len(tparams)==0. If materialized aliases are disabled, there must not be any type parameters.
func NewAlias(enabled bool, pos token.Pos, pkg *types.Package, name string, rhs types.Type, tparams []*types.TypeParam) *types.TypeNameOrigin function #
Origin returns the generic Alias type of which alias is an instance. If alias is not an instance of a generic alias, Origin returns alias.
func Origin(alias *types.Alias) *types.AliasRhs function #
Rhs returns the type on the right-hand side of the alias declaration.
func Rhs(alias *types.Alias) types.TypeSetTypeParams function #
SetTypeParams sets the type parameters of the alias type.
func SetTypeParams(alias *types.Alias, tparams []*types.TypeParam)TypeArgs function #
TypeArgs returns the type arguments used to instantiate the Alias type.
func TypeArgs(alias *types.Alias) *types.TypeListTypeParams function #
TypeParams returns the type parameter list of the alias.
func TypeParams(alias *types.Alias) *types.TypeParamListGenerated with Arrow
