Not miri. I mean the actual ASAN, UBSAN, TSAN, MSAN and LSAN sanitizers that are also commonly used in C and C++ codebases. Descendant is the same: LLVM [1]
> Can you point me to any significant primarily rust codebase that runs sanitizers? I've never heard of that
Not sure what do you mean by that, surely there are. At least the ones who are serious about the development. Sanitizers are part of official documentation in Rust [2].
