people were writing mission-critical C++ when C++ was new / only a few years old; with this in mind, rust is probably good to go with sufficient application/system testing
that said, since C++ & associated tooling exists, there is more of an opportunity cost since, in the context of today, there are more alternatives that could be considered
- carlmr 6y agoI think this is spot on. The tooling is there for C++, but human mistakes are much more prevalent, and the discipline to apply the tooling is not a given. There should be an industry push for certified Rust tooling, it would save the aerospace and auto industry billions. Or you could use the unsexy but also very good ADA 2012, which is already certified.
- pjmlp 6y agoThis is one of the reasons why NVidia went with Ada/SPARK for their security critical firmware project.
- sterlind 6y agoiirc, SPARK has proof capabilities that outstrip the memory-safety guarantees of Rust. basically design by contract, where you can check loop invariants and statically verify complex preconditions and postconditions. I suppose the workflow would be to flesh out and check the abstract design in something like Coq or (maybe) TLAPS, generate a refinement into the SPARK code contracts, then implement the functions. Since the toolchains are verified there shouldn't be much surface area for bugs left.
- pjmlp 6y agoYep, here some very good books about it, specially relevant given the main subject.
