Apparently the concept of users who are not men is "too controversial" in the SerenityOS project, "as to not alienate anyone*".

(*Anyone, as long as you go by he/him, of course.)

@jyasskin It doesn't mention "multiple files", though, just "members" aka "compressed data sets". The RFC doesn't say whether those should represent one file each, or whether they represent chunks of the same file. Fwiw, gzip implementations I've seen all treat it as chunks of a single file, which I think was the original intention of the design: making concatenating transparent to g(un)zip.

🦀 New #rustlang blog post! "Behind the Scenes of Rust String Formatting: format_args!()"

A dive into the dirty details behind format!(), println!() and similar macros, and an exploration of ideas for future improvement.

"programming is serious and not a game [..] stop with the outfits and princess programmer stuff"

I think we should all start writing software and giving talks while wearing princess dresses. ????

?? Yet another version of #rustlang, Rust 1.67.0, has just been released!

This one is a relatively small release. So, short release thread:

? 1/6

A must_use attribute on async functions now does what you expect.

#[must_use]
async fn hey() -> Thing { … }

Now, #[must_use] applies to `Thing`, instead of to the `impl Future<Output=Thing>` (which wasn't very useful).

2/6

std::sync::mpsc has a new implementation, based on crossbeam-channel.

The old implementation had some issues and was hard to maintain. The new implementation fixes some small but long-standing bugs and has better performance.

(The public interface remains unchanged.)

3/6

The integer types now have (integer) logarithm methods: ilog, ilog10, ilog2. (And zero-checking versions: checked_ilog, checked_ilog10, and checked_ilog2.)

ilog2 is implemented using leading_zeros(), so is very efficient.

All of these methods usable in const context too.

4/6

Clippy has a number of exciting new lints: https://github.com/rust-lang/rust-clippy/blob/master/CHANGELOG.md#new-lints

For example, you can now enable #![warn(clippy::manual_let_else)] to tell you about some situations where you could use the recently introduced let-else syntax.
