Hi Jonas,
Is this question in regards to the current or future status of Rust in
Guix? Historically, updating Rust has been considered a core-updates
level change due to the number of dependent packages [0]. Under the
new feature branch workflow there was a recent announcement [1] by the
Rust team that 1.67 is in testing [2].
Can Guix's build farm keep up with Rust's six week release cycle? The
compute looks to be available but I don't recall a discussion for
consideration of storage or a blueprint for pruning old packages.
