Module error_codes 

Error, status and stream-reset code registries defined by draft-ietf-moq-transport-19.

One enum per registry in the IANA Considerations section (Section 15.11). The registry tables list only Name, Code and Specification; the per-code prose in the variant docs is taken from the section each row cites.

from_u64 returns None for any value the draft does not assign. A peer may legitimately send a code from a later draft or a private extension, and an unrecognized code must not be a decode failure at this layer.

Each of these four registries reserves 0x7f * N + 0x9D for greasing (Section 14). That is a range rather than an assignment, so it gets no variant and from_u64 reports it as unknown like any other unassigned value.

Code points inside a registry are not contiguous; the gaps are the draft’s.
