Method Signature

pkg/sql/sem/tree/overload.go:124–132

Signature returns a human-readable signature. If simplify is bool, tuple-returning functions with just 1 tuple element unwrap the return type in the signature.

(simplify bool)

// If simplify is bool, tuple-returning functions with just
// 1 tuple element unwrap the return type in the signature.
func (b Overload) Signature(simplify bool) string {
	retType := b.FixedReturnType()
	if simplify {
		if retType.Family() == types.TupleFamily && len(retType.TupleContents()) == 1 {
			retType = &retType.TupleContents()[0]
		}
	}
	return fmt.Sprintf("(%s) -> %s", b.Types.String(), retType)
}

// overloadImpl is an implementation of an overloaded function. It provides
// access to the parameter type list  and the return type of the implementation.
