We are trading away disk space for faster builds. We could make them faster in some cases by using even more... On the other hand, it would be good to garbage collect those caches.…

That and the existing reply are incorrect. Almost everyone has repeated the same superficial requests and design work and not dug into the problems to come up with a proposal that …

An RFC was recently merged to unblock this: https://github.com/rust-lang/rfcs/pull/3963 The implementation on this has started. Something to keep in mind is https://blog.m-ou.se/ru…

As a prolific PR author, I've found how I communicate has a major factor on how well and quickly people respond to PRs. I've recorded my lessons at https://epage.github.io/dev/pr-s…

As a reviewer, I love type first because it sets expectations for what I'm going to look at. Similar if I'm bisecting or doing other history operations. I don't do automated change…

Not having used uv but being on the Cargo team for Rust, I wish `cargo update` was `cargo lock update` because it is making our life more difficult to add a version requirement upd…

An important part to me that gets overlooked is shared logins. Rust runs the tests of all known Rust projects in a tool called `crater`. I was analyzing a run identifying projects …

I appreciate you recognize there is still a reason for grouping commits into mergeable units (PRs). Some go too far and only want every commit to be independent. I also appreciate …

Yeah, having `cargo test` require another binary like `uv` is not idiomatic. 99% of the time, I should be able to walk up to a Rust project and run `cargo test` and it should just …

Really interested in this for cargo/rustc. We run into issues where we need one or two more colors but all that is left after going for the basic semantic colors is magenta (odd ch…

For me the issue isn't performance but bad hook updating logic. They expect hooks to be managed in isolated repos with exclusive use of tags. I have my gh action and hook in the re…

In Rust, we use workspaces for - splitting up a package into smaller compilation units to speed up builds as llvm doesn't like large compilation units, e.g. I'm assuming this is wh…

> In fact, a code fence need not consist of exactly three backticks or tildes. Any number of backticks or tildes is allowed, as long as that number is at least three Unfortunately,…

There are a couple differen things going on - completions being aware of the subcommand - dynamic look ups for specific values - completions being aware of previous options, flags,…

As I'm not familiar with the npm ecosystem so maybe I'm misunderstanding this but it sounds like they removed support for local publishes (via a token) in favor of CI publishing us…

It reads naturally but I can see people getting tripped up writing this. Worse for changing existing code. Refactor in a way that removes a body? Likely forget to add a breake

I think the switch statement design is a foot gun: defaults to fall-through when empty and break when there is a body. https://c3-lang.org/language-overview/examples/#enum-and-swi.…

Take the example at https://docs.rs/thiserror/latest/thiserror/ - Struct variant fields are public, limiting how you evolve the fields and types - Struct variants need non_exhausti…

I think we should provide the building blocks (display, etc like derive_more) rather than a specialized version one for errors (thiserror). I also feel thiserror encourages a publi…

> It may have been nice to expose some reasonable defaults for code coverage measurements too. Would love built in coverage support but investigation is needed on the design ( http…

For Cargo, - synchronization operations are implicit so we need to re-resolve to confirm the lockfile is still valid. We could take some short cut but it would require re-implement…

TOML as a format doesn't make sense for streaming - Tables can be in any order, independent of heirarchy - keys can be dotted, creating subtables in any order On top of that, most …

Lockfiles aren't an issue. It is all the dependencies themselves.
