Returns the type name of the value as a string.
Returns reference to the inner [CustomValue] if this is a Custom variant.
Attempts to decode a Custom variant into a concrete CustomDataType .
Returns None if this is not a Custom variant, the type tag doesn’t
match, or decoding fails.
Performs copy-assignment from
source.
Read more Formats the value using the given formatter.
Read more Deserialize this value from the given Serde deserializer.
Read more Source § Encodes a Value as [discriminant: u8] + [inner_type.encode()].
For Null, only the discriminant byte is written.
For Custom, the encoding is [discriminant] + [tag_len: u16 LE] + [tag_bytes] + [data_len: u16 LE] + [encoded_bytes].

Returns the size in bytes of the encoded data type.
