Method Encode

pgtype/pgtype.go:1969–1994

Encode appends the encoded bytes of value to buf. If value is the SQL value NULL then append nothing and return (nil, nil). The caller of Encode is responsible for writing the correct NULL value or the length of the data written.

(oid uint32, formatCode int16, value any, buf []byte)

// (nil, nil). The caller of Encode is responsible for writing the correct NULL value or the length of the data
// written.
func (m *Map) Encode(oid uint32, formatCode int16, value any, buf []byte) (newBuf []byte, err error) {
	if isNil, callNilDriverValuer := isNilDriverValuer(value); isNil {
		if callNilDriverValuer {
			newBuf, err = (&encodePlanDriverValuer{m: m, oid: oid, formatCode: formatCode}).Encode(value, buf)
			if err != nil {
				return nil, newEncodeError(value, m, oid, formatCode, err)
			}

			return newBuf, nil
		} else {
			return nil, nil
		}
	}

	plan := m.PlanEncode(oid, formatCode, value)
	if plan == nil {
		return nil, newEncodeError(value, m, oid, formatCode, errors.New("cannot find encode plan"))

// SQLScanner returns a database/sql.Scanner for v. This is necessary for types like Array[T] and Range[T] where the
// type needs assistance from Map to implement the sql.Scanner interface. It is not necessary for types like Box that
