How to get latest Cargo version

pdeva · November 13, 2023, 8:17pm

latest version of Cargo even in unstable is at 1.72.1.

1.73 has been out for a while now. Is there any way to get the latest version?

## Description of changes This upgrade unfortunately removes MIPS support, as… it has been [dropped to Tier 3][1] and so bootstrap tarballs are no longer provided. It looks like it was dropped due to multiple codegen bugs, and lack of maintenance, so bringing it back would probably involve engaging with Rust/LLVM upstream on those.

This is done with overlays, as mentioned in the wiki.

Check out either fenix or rust-overlay.

They both provide a way of having different Rust toolchains, for example, the latest stable one or nightly.
