* gnu/packages/rust.scm (rust-next): New exported variable, formerly known as
"rust-1.65".
---

Hi,

This patch allows to install the latest Rust, here 1.65, while the default
Rust used by the cargo build system is 'rust' (here 1.60). Instead of,

guix shell -e '(@@ (gnu packages rust) rust-1.65)'

it allows "guix shell rust-next"; similarly as emacs vs emacs-next.

Cheers,
simon

For the reasons I outlined in https://issues.guix.gnu.org/62064#5, we can't
just export RUST-1.65 as RUST-NEXT, unfortunately...

Agreed. If there is a need for newer public rust version, please go
through the maintainers' note above the 'rust' variable:

;;; Note: Only the latest versions of Rust are supported and tested. The
;;; intermediate rusts are built for bootstrapping purposes and should not
;;; be relied upon. This is to ease maintenance and reduce the time
;;; required to build the full Rust bootstrap chain.
;;;
;;; Here we take the latest included Rust, make it public, and re-enable tests
;;; and extra components such as rustfmt.

Usually the whole collection keeps building with the latest rust version
as it's backward compatible, I think, so it's not as much work as it may
look like.

OK to close?

I'd rather work on upgrading the whole rust ecosystem packaged in Guix than
keep a newer version of rust working while fielding questions about why it's
not yet the default.

I understand that the current rust-1.65 is unusable by itself because it
misses some part as explained by https://issues.guix.gnu.org/62064#5.

However, I do not understand that…

How 1.60 could be the latest compared to 1.65?

Said differently, why 1.65 is packaged if it is unusable? Even, what is
the point to maintain 1.61, 1.62, 1.63, 1.64 and 1.65 if they are
unexported and unusable? These 5 versions are not part of the bootstrap
of 1.60.

If the work for updating the Rust ecosystem is a work in progress and
this work is currently in the middle, why is it not done in a dedicated
branch?

simon

Yes. :-)

Although the confusion pointed by #62064 [1] is not fixed.

Perhaps it was an oversight, or preparation for the next bump? (getting
to know the hash and any new inputs needed, etc., without doing the
actual work of migrating the leaf rust definition to the latest rust).

See above justification. It's an internal package. You won't find it
at the CLI, so you can't really say that "it's packaged" :-).

With the new teams flow, I hope that can be used for that way too. I'd
prefer always having the leaf rust package exported and no newer
trailing but not there yet variants.

I think we all agree. We just need a champion to do it :-).

That is a question more than a problem (the real problem being that our
rust is old -- 1.60), which I think we have already discussed and agreed
is sub-optimal and probably stemmed from a misunderstanding :-).

I am closing this one and I will close the other one since the work is
clear: champion the Rust ecosystem upgrade. :-)
