hap-model

The HomeKit accessory attribute database for hap-rust (Milestone 6). Transport-agnostic: it parses and serializes JSON and never touches the network.

What it does

• Parse GET /accessories JSON into a typed Accessory → Service → Characteristic tree (parse_accessories).
• Build and parse /characteristics read / write / subscribe requests (build_read_request, parse_read_response, build_write_request, build_subscribe_request).
• Model characteristic formats (CharFormat), decoded values (CharValue), permissions (Perms), and value constraints.
• Code-generated ServiceType / CharacteristicType tables with short-UUID expansion and default formats.
• An optional AccessoryDatabase<E: RequestExecutor> for typed access given a caller-supplied request executor (the controller wires in a secure session).

Codegen

The HAP type tables are generated from xtask/model/hap-types.json:

cargo xtask codegen-hap-types

This rewrites src/generated.rs, which is committed.

Status

Pre-1.0. See the workspace roadmap.
