func NewSignatureType ¶

func NewSignatureType(recv *types.Var, recvTypeParams, typeParams []*TypeParam, params, results *types.Tuple, variadic bool) *types.Signature

NewSignatureType creates a new function type for the given receiver, receiver type parameters, type parameters, parameters, and results. If variadic is set, params must hold at least one parameter and the last parameter's core type must be of unnamed slice or bytestring type. If recv is non-nil, typeParams must be empty. If recvTypeParams is non-empty, recv must be non-nil.
