Could you share the output of ‘guix describe’ and that of ‘uname -m’ so
we can understand how to reproduce the issue?

FWIW, with a commit of today, Rust 1.58 is available on x86_64-linux:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=4716cea6256523a8ecf90a426d675bfb7620f3e4 -- build 
-n -e '(@@ (gnu packages rust) rust-1.58)'
