rust 1.61.0 support

[SUPERCILEX]

Unfortunately I need a number of nightly features, so no stable version of the compiler will work. I don't expect this to change anytime soon. You'll want to use the prebuilt binaries or rustup: https://doc.rust-lang.org/cargo/getting-started/installation.html

[jelmd]

Hmmm, ok. Idea was to provide it on our cluster nodes. But there only packages are allowed and I build the missing ones with supported compilers, only. Anyway, if users think they need it, they can build, or download, or bench on their own risk ... ;-)

[jelmd]

BTW: x86_64-unknown-linux-gnu binaries do not work as well, because they are linked against GNU libc > 2.31.

[SUPERCILEX]

Hmmm, you'll probably need to use the *-musl variants then (as they're statically linked). 20.04 is pretty old at this point.

[andreasstieger]

I checked and the nightly features you are using are not in 1.68 either. Your choice, but even rolling distributions would appreciate if you found a way to target current rust stable.

[SUPERCILEX]

I really don't want to have to copy all of once_cell, but I dropped some features that should be implemented with other nightly features anyway. So basically this is pending once_cell stabilization.

[andreasstieger]

Thanks. For once_cell it seems there is a crate version at https://docs.rs/once_cell/latest/once_cell/ If that is the last one this would bring fuc to the realm of rust stable

[SUPERCILEX]

Lemme first see if I can get once_cell moving again: it finished its fcp back in January, so it's a little surprising that it hasn't been merged yet. Otherwise, are people building from master or tags? I could potentially just apply a patch before tagging that has stable support and keep master on nightly.

[andreasstieger]

Distros can build from any git reference including tags, and any combination of patches on top, including non-contiguous series. I'll volunteer my openSUSE package for fast feedback.

[SUPERCILEX]

Hmmm, ok. I don't want to make any guarantees that I won't return to requiring nightly, but it's currently trival to support building the binaries with stable. cargo test still requires nightly, but that isn't a problem I hope/assume.

Triggered a release: https://github.com/SUPERCILEX/fuc/actions/runs/4536253663
Patch applied in 1.1.7: e2285aa

[SUPERCILEX]

As a sanity check, it'd be helpful if someone could cargo install rmz cpz on stable rust.

[andreasstieger]

Looks good with (at least) rust 1.68, package works. For cargo install rmz cpz see separate issue referred below.
