SemVer is tricky in all languages. But in #rustlang it's easier than ever before!

By the end of 2024, cargo-semver-checks' capabilities were growing exponentially: 30 -> 57 -> 120 lints. We now end 2025 with 242 lints — 122 new lints were merged this calendar year 🎉

The exponential continues!
Screenshot from the cargo-semver-checks 2024 year in review post featuring a diagram of the number of lints at the end of each calendar year. 2022 ended with 30 lints, 2023 ended with 57, 2024 ended with 120 lints. Link to the post: https://predr.ag/blog/cargo-semver-checks-2024-year-in-review/

What was the person thinking 🤣
In reddit, one person complained that the official rust book was written by AI because his AI detector reported it as 100% written by AI

Time to spend all of the money you’d normally spend on regularly priced RAM upgrades on sponsoring devs building oss + native Rust (or swift, or go) desktop UI frameworks/toolkits instead!

(Then only the rust developers are sad we need more RAM for actually compiling the apps)
danhon.com Dan Hon @danhon.com · 20d
It would be hilarious if spiking RAM prices were the cause of a move away from Electron/webview-based apps to native apps. I've seen arguments from gamers* that unoptimized games right now are on the verge of unethical*.

🦀 Love the compile time assertions in Rust

Instead of panicking at runtime for invalid constant values, catch it at compile time:

``rust
const fn get_top(freq: f64, div_int: u8) -> u16 {
...
assert!(
result <= 65535.0,
"error msg"
);
...
}
```

#rustlang
Calculating pwm top using const function. Validating top ensure within maximum top allowed before converting into u16. Using assert to validate at compile time
