Hibana enforces choreography-derived multiparty protocols in no_std Rust

github.com 26 min read Editor score 7/10

Hibana projects a global choreography into per-role programs and checks protocol steps before progress commits, using compact descriptors and caller-provided storage. The approach is relevant to engineers building constrained, protocol-safe distributed software.

What: Hibana is a no_std Rust runtime that enforces multiparty protocols projected from one global choreography.
How: It projects compact role programs, then checks each send, receive, or route step against the program before progress commits.
Why it matters: Caller-provided storage and compact descriptors keep the runtime usable without an allocator and prevent protocol growth from inflating endpoint types.

A choreography is projected into role programs that endpoints execute using a transport. Sketched from the article's own text.
