The source of the standard Rust Hello World program with the generated assembly before and after the change. The before version has 11 instructions and stores 56 bytes on the stack. The after version has 3 instructions and stores no data on the stack.

🦀 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! 🎉

does your tool spawn processes? then LOOK UP the absolute path of the process you're running first. if that fails, log that in great detail. if it succeeds, log the absolute path of the path you found. if the process fails, in the failure log, include the absolute path of the process that failed.

Whenever I notice LLMs being "not great" at Rust, it's because they're trying to write, JS or Go, but in Rust. Which is.. the same reason why a lot of humans are having a bad time with Rust 🙃 — writing types first, then stub functions, then tests, then implementation, that's a happier way.

Meme not from the article. The rust compiler is a giant soldier who is protecting other soldier(that is we). Compilers helpful error message help us

✨ Flattening Rust's Learning Curve

This is the most important part:

>Treat the Borrow Checker as a co-author, not an adversary

> Forget what you think you knew about programming and really start to listen to what the compiler

GitHub - pgdogdev/pgdog: Horizontal scaling for PostgreSQL with automatic sharding. Horizontal scaling for PostgreSQL with automatic sharding. - pgdogdev/pgdog

pgdog is a sharder, connection pooler and load balancer for PostgreSQL.

Written in Rust, scales databases horizontally without requiring changes to application code.

Issues · facet-rs/facet Rust const and no_std reflection — the last derive you'll ever need - Issues · facet-rs/facet

So many ideas that I'm excited about in the issue tracker github.com/facet-rs/fac... — I know the public-facing documentation is lagging behind but better underpromise and overdeliver I suppose.

That’s why Ruby’s `select` is a better name.

A screenshot of a terminal showing the application panicked, error deserializing JSON, and then there's a bunch of lines of JSON. The line numbers are dimmed, and the JSON text itself is the default style, and then there's a little curve message under the N that says unexpected character N, because I have not implemented support for nulls in this latest rewrite yet.

probably not its final form but I kinda like this reporting

GitHub - fasterthanlime/timelord: Save/restore timestamps when building Rust code in CI (to allow fresh checkouts but taking advantage of incremental builds) Save/restore timestamps when building Rust code in CI (to allow fresh checkouts but taking advantage of incremental builds) - fasterthanlime/timelord

Threw together a quick tool to restore timestamps between CI builds so cargo won't do unnecessary rebuilds — I haven't tested it in my CI yet but I figure it's more reliable & faster than a bunch of bash or node.js

It's probably also how our brains work too. Which is why I don't trust it to do complex calculations by itself!

Async Rust book arriving tomorrow

Looking forward to it
