Well, I know few about Rust and I guess it is because using =E2=80=99rust-1= .65=E2=80=99 as default Rust is a world-rebuild. --8<---------------cut here---------------start------------->8--- $ guix refresh rust -l | cut -f1 -d':' Building the following 4560 packages would ensure 6637 dependent packages a= re rebuilt --8<---------------cut here---------------end--------------->8--- > This is especially troublesome for Rust on Guix because of both how > fast its ecosystem moves onto new language/tooling features, and > because using rustup (the solution for this on other slow-moving > distros) relies on pre-built executables that don't work > out-of-the-box on Guix.=20 Well, the issue when exporting =E2=80=99rust-1.65=E2=80=99 is that it would= possible incompatible with the Rust packages provided by Guix and compiled with =E2=80=99rust=E2=80=99 (1.60). Maybe, one could imagine a package transformation =E2=80=99package-with-explicit-rust=E2=80=99 as it is done for Python and O= Caml. Cheers, simon
