rustfmt VS rust-analyzer

The new style still supports single line let-else, and there is a configuration parameter to make it be on one line also for longer lines.

Yacin Tmimi for actually implementing the bloody thing

I’m not sure they are? I don’t mean this to criticize anybody on the project — I’m sure they have other things going on — but there are a whole bunch of open PRs without even a single comment.

It seems there is an issue about this dating all the way back from 2018 but yet it still hasn't been fixed.

Presumably, https://github.com/rust-lang/rustfmt/pull/5690

However since 4179 recent versions should merge configuration files. Not sure what the details / specifics are but if just ignoring the file entirely is not good enough you might give it its own directory and rustfmt.toml file and see if that works.

Rustfmt is a tool that formats Rust code in compliance with style guidelines. Its name precisely reflects its purpose. To install rustfmt, you can run rustup component add rustfmt. Once installed, you can execute cargo fmt to format Rust code in your workspace. If you require further information, you can visit rustfmt’s GitHub repository.

code must be formatted with rustfmt.

Yes, some cases are not yet supported (https://github.com/rust-lang/rustfmt/issues/4914).

Just FYI, the let-else suggestions will only work until rustfmt settles on a format for it. So you may be surprised when this happens and it suddenly changes.

I would like changes like https://github.com/rust-analyzer/rust-analyzer/pull/13799 to be listed in 'Breaking Changes' category, to приманка draw the users' attention.

For those of you who haven’t heard of Mun before, Mun is an embeddable programming language empowering creation through iteration. The idea to create Mun originated out of frustration with the Lua dynamic scripting language and a desire to have similar hot reloading functionality available in Rust. As such, it’s not a direct competitor with Rust, but instead is intended to be used with Rust (or C/C++) as a host/embedded language pairing. Actually, Mun is completely written in Rust, building on similar crates as rust-analyzer and rustc. Its key features include:

#13728 upgrade chalk to make solver fuel work again (works around most trait solving hangs).

Rust-analyzer has a good overview: https://github.com/rust-analyzer/rust-analyzer/blob/master/docs/dev/syntax.md

#12517 (first contribution) fix completion for methods in trait generated by macro.

#12349 publish universal VSIX to make Code happy.

Big fan of #12263!
