I'm curious to hear where you've seen Rust not scaling to large teams or codebases?

There's nothing fast about zero-terminated strings. In fact, many operations on them are much slower than sane alternatives, because they first have to scan the entire string to compute its length. You can't even create a temporar

My hunch is that for most consumers, there's just no point in getting anything above 1 GbE today, even for their central switch. 1 Gbit/s is more than enough for 5x 4K video streams from their NAS, plus a very fast Internet connec

Although I strongly disagree with pron's point, format strings aren't limited to printing them to stdout. There's format!() , for example, which returns a String for further use, and you could even write a sql_query!() mac

You don't need format strings to create vulnerable queries. If you can't use them, this code: let query = format!("SELECT name FROM users WHERE id = {}", user_id); can easily be replaced by this: let mut q

by adwn 5y ago
You're still misunderstanding the purpose of format strings. They're not a templating engine for SQL, HTML, whatever. There's nothing to sanitize.
531.
by adwn 5y ago
How is that related? The new format strings must be static literals because they're decoded at compile time. It is impossible to use them for any kind of code injection.

For most of my projects, I would switch from Rust to a GC language in a heartbeat, provided that it 1) is as safe and as fast as Rust, or at most 1.5x slower 2) offers "fearless concurrency" and easy, safe, and efficient paralle
