rusp is the Rust USP toolkit, brought to you by Axiros!
Rust is a fast and safe systems programming language.
USP (or User Services Platform) is a new protocol for management of connected devices, maintained and developed by the Broadband Forum.
Axiros is a leading company for device management.
rusp is a toolkit, written in Rust, providing support to work with USP records and messages which are encoded in Protobuf bytestreams.
While a Protobuf schema exists which allows generating bindings for several commonly used programming languages, those are either uncomfortable to use and/or highly unsafe. By leveraging the strong Rust type system and the strict compiler, Rust is capable of detecting many incorrect or incomplete uses of the Protobuf encoding at compile time which allows for confident use of the USP protocol.
The toolkit includes: * Generated lowlevel Rust protobuf bindings * A library providing: * Higher level access to serialisation/deserialisation functionality * Convenience functions to generate messages * Pretty printing of USP records and messages * Unittests and documentation (including doctests/examples) * A rusp binary granting access to library functionality via command line. Included functionality at the moment are: * Decoding of USP Msg Protobuf bytestreams from standard input * Decoding of USP Msg Protobuf bytestreams from file(s) * Decoding of USP Record Protobuf bytestreams from standard input * Decoding of USP Record Protobuf bytestreams from file(s) * Extraction of USP Msg Protobuf bytestreams from the payload of a USP Record Protobuf bytestream
You may use this crate however you like under the BSD 3-Clause License.
The toolkit is still far from feature complete but already a big aid in our product development and also helped to find one or the other discrepancy in the standard.
Feel free to spread the word or drop us a note if you like it. Collaboration on this crate is highly welcome as are pull requests!
