A type that provides a view into an encoder’s storage and is used to hold the encoded properties of an encodable type sequentially, without keys.
Encoders should provide types conforming to
UnkeyedEncodingContainer for their format.
var count: Int
The number of elements encoded into the container.
Encodes a reference to the given object only if it is encoded unconditionally elsewhere in the payload (previously, or in the future).
Required. Default implementation provided.
A concrete container that provides a view into an encoder’s storage, making the encoded properties of an encodable type accessible by keys.
