Opening Cargo.lock or looking at the output of cargo-geiger is a good excuse, often thanks to the initial "WTF are they doing???", to audit other crates and learn more about the ecosystem you are relying on.

Turns out the TokenStream implementation of rust-analyzer's proc-macro server is super slow when it comes to one of the most common proc-macro operations: concatenation. I noticed that in Zed's codebase, there were ~4 derives that just straight up together took 8 seconds to expand in rust-analyzer.

the verge's reviews program has always been the heart of the site and one reason we jealously protect it and refuse to do brand deals is so we can just say the products are bad www.theverge.com/report/82215...

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉
