Implementing Multiparty Session Types in Rust

Abstract

Multiparty Session Types (MPST) is a typing discipline for distributed protocols, which ensures communication safety and deadlock-freedom for more than two participants. This paper reports on our research project, implementing multiparty session types in Rust. Current Rust implementations of session types are limited to binary (two-party communications). We extend an existing library for binary session types to MPST. We have implemented a simplified Amazon Prime Video Streaming protocol using our library for both shared and distributed communication transports.
