libs-team VS sccache

In rust, both release and debug builds use a release version of the runtime. The bugs the debug version is meant to catch are much more difficult to hit in rust (often but not always requiring unsafe). There isn't currently a feature to use the debug runtime in rust-- you can only change C to match for those debug builds.

Note that this has been discussed at length (and I do mean "at length") here: https://github.com/rust-lang/libs-team/issues/72

The Compiler Team, especially the Diagnostics Working Group that improves compiler error messages. The Libs Team, for work on the contents of the standard library documentation

See https://github.com/rust-lang/libs-team/issues/72#issuecommen... for what I believe is an exhaustive list of possible ways of helping the situation.

The point is how the MSRV of a popular crate affects this dynamic for other crates. For an even more extreme example than time, see here for libc, with many heavyweights offering opinions: https://github.com/rust-lang/libs-team/issues/72

In case you haven't seen it yet, there is a very long discussion surrounding MSRV policy of the libc crate on rust-langs github repo. It's about a library, not a binary, but I think there's a lot of information in the thread, some of which will also apply to binaries.

Would you mind sharing your use case for being stuck with a particular version of Rust and why you can't upgrade? In particular with the libs team: https://github.com/rust-lang/libs-team/issues/72

Compare Stepanov's brilliant design of the STL to Rust's current reworking of their 'binary search api'. https://github.com/rust-lang/libs-team/issues/81

Maybe 'memory safety' isn't the most important thing in this world. To me, writing software that does useful things in the simplest and most correct way is what matters. I get the feeling it's harder to understand my program's correctness with Rust (I mean algorithmic correctness). The C++ standard library has time and space complexity for every algorithm. I'm not seeing that's the case with Rust (correct me if I'm wrong).

There's also the pretty fundamental libc crate that wants to choose an MSRV policy and you can see the full discussion here: https://github.com/rust-lang/libs-team/issues/72

Use icecream or sccache. sccache supports distributed builds.

Worth noting that the first commit in sccache git repository was in 2014 (https://github.com/mozilla/sccache/commit/115016e0a83b290dc2...). So I suppose that what "happened" happened waay back.

If you have lots of shared dependencies, maybe try sccache?

I'm going to set up sccache [0] to use it tomorrow. We use MSVC, so EFS is off the cards.

I think the primary benefit of pre-built procmacros will be for build servers which don't use a persistent cache (like sccache), since they have to compile all dependencies every time. But IMO improved support for persistent caches would be a better investment compared to adding support for pre-built procmacros.

Checkout https://github.com/mozilla/sccache

https://github.com/mozilla/sccache is another option which addresses the use cases of both icecream and ccache (and also supports Rust, and cloud storage of artifacts, if those are useful for you)

That being said a compilation cache, eg the de-facto standard for Rust: sccache (https://github.com/mozilla/sccache) will help to compile and store some of the build artifacts centralized - still for each crate version + build profile (RUSTFLAGS) combination.
