Module cbor 

Concise Binary Object Representation (CBOR) formats.

This module implements the basic generic data model from RFC 8949. It is allocation-gated because recursive generic values necessarily contain Boxes and Vecs. Definite byte and text strings borrow directly from the input; allocation is needed only for fragmented strings and recursive items.

CborFmt<false> accepts the well-formed representation variants described by RFC 8949. CborFmt<true> additionally requires preferred integer, length, and tag arguments and rejects indefinite-length items (RFC 8949 section 4.2.1).

Limitations

• Map-key ordering is not yet enforced in CborFmt<true>.
• Floating-point widths are retained in CborFloat, so shortest-width floating-point normalization is likewise not yet imposed.

See the CBOR guide for the runtime workflow, ownership model, and deterministic-profile scope.
