GoKawiilNew Rust library Hibana enforces multiparty protocols from a single choreography
Hibana is a new no_std Rust runtime that lets developers define a single global choreography describing a protocol among up to 256 roles, which it then projects into a compact program for each role. Every send, receive, or routing step at each endpoint must match its projected program before the step can proceed, and the system requires no allocator, using caller-provided storage instead.
GoKawiil's interpretation of the reporting above, not reported fact.
By deriving per-role programs from one global description rather than generating a distinct Rust type for each protocol state, Hibana aims to keep endpoint code compact even as protocols grow in complexity, according to the project's documentation. The authors note the tool checks protocol correctness locally at each endpoint and per session, not as a single distributed guarantee, meaning developers must still account for network, codec, and scheduling conditions themselves if a protocol is split across sessions.
- Hibana projects one global choreography into compact per-role programs for up to 256 roles using a one-byte role ID space.
- It is no_std with no allocator requirement, using caller-provided storage and a transport-neutral integration trait.
- It enforces protocol correctness per attached endpoint and per session, not as an automatic distributed-system guarantee across split sessions.
