Function MakeID

internal/jsonrpc2/messages.go:30–40

MakeID coerces the given Go value to an ID. The value should be the default JSON marshaling of a Request identifier: nil, float64, or string. Returns an error if the value type was not a valid Request ID type. TODO: ID can't be a json.Marshaler/Unmarshaler, because we want to omitzero. Simplify th

(v any)

// Simplify this package by making ID json serializable once we can rely on
// omitzero.
func MakeID(v any) (ID, error) {
	switch v := v.(type) {
	case nil:
		return ID{}, nil
	case float64:
		return Int64ID(int64(v)), nil
	case string:
		return StringID(v), nil
	}
	return ID{}, fmt.Errorf("%w: invalid ID type %T", ErrParse, v)

// Message is the interface to all jsonrpc2 message types.
// They share no common functionality, but are a closed set of concrete types
