Conforming Types SIMD Instance Methods func encode(to encoder: Encoder) throws Required Encodes this value into the given encoder. If the value fails to encode anything, encoder will encode an empty keyed container in its place. This function throws an error if any values are invalid for the given encoder's format. Parameter encoder: The encoder to write data to. Declaration func encode(to encoder: Encoder) throws
