What’s better than UnitTests almost being ready for deployment in TianoCore? How about using those UnitTests to validate a native Rust port of one of our VarCheck libs?
Building upon Jiewen’s work (among others) I’ve finally managed to prototype a port of the UefiVariablePolicyLib to Rust, and have shown that it can build as part of our normal CI process and run the same UnitTests that are used for the C version… https://github.com/corthon/edk2-staging/tree/rust_and_tests There is a Readme.md in the root directory with a “Notes for this branch” section. All of those steps are important to get Rust set up correctly. You can run a CI build of MdeModulePkg with the “-t NOOPT” target and it will build the UnitTests. It will build one version against the C library, and another against the Rust library. You can also run native Rust test cases by going to https://github.com/corthon/edk2-staging/tree/rust_and_tests/MdeModulePkg/Library/UefiVariablePolicyLibRust And running “cargo test”. I acknowledge that this code is a little rough. It’s definitely a prototype, but one that I’m excited about and thing that it can be used as a pattern for interop with other core libraries. I even found a couple small bugs in the original library through the process of porting to Rust, since Rust is so pedantic about covering all possible cases. Anyway, super interested in any feedback or advice for improvement. 😊 - Bret PS. Thanks again, Jiewen, for laying the groundwork. I’ve seen several of your contributions to Rust and the UEFI prototype while working on this. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
