Module wire 

Driver-shared wire format for serialising aozora parser output.

Three driver crates (aozora-ffi, aozora-wasm, aozora-py) all need to project the borrowed-AST output to a stable byte stream. This module is the single authority for that projection — each driver calls into here and is guaranteed bit-identical output across language boundaries.

Schema envelope

Every wire JSON has the shape

{ "schema_version": 1, "data": [ /* …entries… */ ] }

SCHEMA_VERSION is bumped on any breaking change to the serialised shape (variant additions, field renames, envelope changes). Clients that read the wire format SHOULD branch on the version to decide their handling — schema 1 makes no guarantees of forward-compatibility with later schemas.

Stability vs. non_exhaustive

Both crate::Diagnostic and crate::AozoraNode are #[non_exhaustive] upstream so the library can add variants in minor releases. The wire format protects callers by:

• falling back to kind: "unknown" for unrecognised variants, and
• bumping SCHEMA_VERSION when new variants land in the wire (so a client that branches on the version can react before "unknown" shows up in production traffic).

Constants

SCHEMA_VERSION

Wire-format schema version. Bumped on any breaking change to the serialised shape (variant additions, field renames, envelope changes).

Functions

container_kind_str 🔒

envelope_schema 🔒

Wrap the per-entry schema in the canonical {schema_version, data: […]} envelope. The envelope shape is shared by all four wire functions; only the inner item schema varies.

schema_container_pairs

JSON Schema for the serialize_container_pairs envelope output.

schema_diagnostics

JSON Schema (draft 2020-12) describing the serialize_diagnostics envelope output.

schema_nodes

JSON Schema for the serialize_nodes envelope output.

schema_pairs

JSON Schema for the serialize_pairs envelope output.

serialize_container_pairs

Project an AozoraTree’s container open/close pair table into a { schema_version, data } JSON envelope.

serialize_diagnostics

Project a slice of Diagnostic into a { schema_version, data } JSON envelope. Every entry has the shape { kind, span: { start, end }, codepoint? }.

serialize_envelope 🔒

serialize_nodes

Project an AozoraTree’s source-keyed node side-table into a { schema_version, data } JSON envelope.

serialize_pairs

Project an AozoraTree’s pair table into a { schema_version, data } JSON envelope. Every entry has the shape { kind, open: { start, end }, close: { start, end } }.
