Module format 

Wire format constants and documentation. Canonical binary format rules.

Version 0.1 intentionally defines one binary representation per supported value:

• integers are fixed-width little-endian,
• bool is exactly 0x00 or 0x01,
• strings are UTF-8 bytes prefixed by a u32 little-endian byte length,
• vectors are prefixed by a u32 little-endian item count,
• Option<T> and Result<T, E> use one-byte tags,
• fixed arrays and tuples encode fields in declaration order.

Floats, pointer-sized integers, hash maps, unordered maps, schema negotiation, and non-canonical alternatives are not part of this initial format. They are omitted because their representation or ordering can be platform-dependent, ambiguous, or outside this crate’s first-version scope.

Generic fixed-array decoding ([T; N]) requires the alloc feature in this version because the crate forbids unsafe code and Rust 1.85 does not provide a stable fallible array initializer. In no-alloc builds, [u8; N] decoding is available because it can be filled directly from the source without heap allocation.
