Specifying Message Formats with Contiguity Types

LIPIcs-ITP-2021-30.pdf (0.6 MB)


We introduce Contiguity Types, a formalism for network message formats, aimed especially at self-describing formats. Contiguity types provide an intermediate layer between programming language data structures and messages, offering a helpful setting from which to automatically generate decoders, filters, and message generators. The syntax and semantics of contiguity types are defined and used to prove the correctness of a matching algorithm which has the flavour of a parser generator. The matcher has been used to enforce semantic well-formedness conditions on complex message formats for an autonomous unmanned avionics system.
