Module core 

Type tags used in the senax binary format.

These tags are written as the first byte of each encoded value to identify its type and optimize decoding. Most users do not need to use these directly.

• Primitives, Option, String, Vec, arrays, maps, structs, enums, and feature types each have their own tag(s).
• Tags are stable and part of the wire format.
