When using the Python script:

timestamp = ScaleDecoder.get_decoder_class('Timestamp', ScaleBytes(timestamp_bytes_array)).decode()

it seems that the decoder expects the size of the array to be exactly equal to the object to be decoded. This is equivalent to the behavior of the DecodeAll trait in rust, where the remaining bytes after decoding must be zero.

How can I, in Python, do whatever is equivalent to Decode trait in rust, where the number of remaining bytes, after decoding, can be > 0, so that I can decode a stream?

There is kwarg you can pass to the decode() function, so it won't check the remaining bytes: decode(check_remaining=False).

I don't have much context of your use-case, but I assume you have added a custom type definition Timestamp to the type registry? Because by default there is no type with that name.
