Struct WireTypeRegistry 

pub struct WireTypeRegistry { /* private fields */ }

A program-derived registry of every struct/enum schema, shared by both ends of a Logos↔Logos link (each side builds it from the SAME program type definitions). Every type gets a stable small id — canonical by fingerprint, so declaration order is irrelevant and sender + receiver always agree. The codec ships the id instead of the type/field NAMES, and the receiver — running the same program — resolves it. This is the “duh, you use that” default that drops names off the wire entirely.

Implementations

impl WireTypeRegistry

pub fn new(schemas: Vec<(String, Vec<String>)>) -> Self

Build from (type_name, field_names) struct schemas. Field names are sorted (the codec’s canonical order), duplicates collapsed, and the set ordered by fingerprint so two peers that declared the same types in any order assign identical ids.

pub fn with_enums(self, enums: Vec<(String, Vec<String>)>) -> Self

Add enum types (type_name, ordered_constructors). Constructor order is preserved (the wire ships a constructor index); the enum set is ordered by fingerprint so both peers assign identical enum ids regardless of declaration order.

pub fn epoch(&self) -> u64

A content hash of this registry’s WHOLE type set — the registry EPOCH advertised in the handshake. Two peers that declared the SAME struct + enum types (in any order) compute the same epoch, so when their epochs MATCH they may elide type NAMES from the wire (type-id). 0 for an empty registry — no shared types, so never elide. Deterministic: folds the per-type fingerprints, which are already in canonical fingerprint order.
