Nice library! Manipulating money is probably trickiest thing since time was invented. Library looks very usable. I have to ask though: > val transactionFee = 1.25.percent() // 1.5% How is it 1.5?

So is /tmp a ramdisk? I have 64GB DDR4, but overclocked to double Infinity Fabric timings i.e. 3600 Mhz (it might be different for DDR5/ Zen4-5). I ran this on MSVC toolchain on windows. With like 43% memory taken by various Firef

I have 5900X, and I got like 4m34s build time on Windows (which should be slower). What memory are you using? Are you overclocking? Are you using SSD?

Here is another. Serde moving to binary blobs. - Does it alter API? No. - Does it change behavior? No. - Does it alter a public promise? No. - Is it SemVer violation? Nope. What is the problem then? Reproducible builds of NixOS and similar

Honestly, impressive work. Getting any language on bare metal is hard work. That said is Ada Spark toolchain proprietary still?

Java isn't that restrictive. Rust's type system is much more restrictive and customizable. That said, a good way to think about programs is a series of restrictions, i.e. invariants. Truth be told, only Ada Spark so far really emb

> "One class per file". Wait. What? Neither Java nor Rust limit class/struct per file. You must mean public class per file. As a fellow Java dev, no it doesn't look like Java at all. Maybe it looks a bit like Kotlin,

I thought you wanted to prevent transitive dependencies. For sandboxing crates, as JoshTriplett said it's another can of worms.

To a point. Let's say you're optimizing a backend written in TS on Amazon, sure it's cheaper to hire guys to optimize it, but at some point it won't be. Either you need some really high class talent to start optimizing s

While there are trucks of nightly only features, some are stuck there for a good reason. Specializations allow unsound behavior in safe Rust, which is exactly what nightly was supposed to catch.

Yes, I'm saying in those cases it does make some sense to rewrite it in Rust.

From security perspective I agree but what if you want to be rid of GC or just reduce your overall resource consumption?

Even i5 will only make it around twice as slow[1]. So from 5min -> 10min. And that's a relatively pessimistic scenario - huge number of dependencies, slow processor (i5), fresh build. In incremental build, it goes from minutes to se

You're overestimating the budget needed for the rig. Would working with a Windows 7 era laptop and Rust suck? Yes. But so would anything else. I'm on a 4-year-old PC, granted it's 5900X, 3800 MHz RAM and my numbers are derive
