Bun is being ported from Zig to Rust

"Claude, migrate bun to Rust, make no mistakes"

I hope they ship and use this. It’ll be a super interesting case study in a few years.

> Read this whole document before writing any code.

Hm does that actually work?

Edit: in a way that can be verified, and not the AI tool saying it did

I guess it's like Trump saying, "I'll take Greenland too..."

April 26th - Bun announces they used AI to fork Zig so they could make an optimization for a 4x improvement

April 27th - Zig contributor mlugg clarifies why the specific optimizations Bun did were ill advised and wouldn't have been accepted in Zig, regardless of AI use [1]

May 4 - Bun is looking into Rust as an alternative.

This, to me, seems like total whiplash. Has anyone at Bun made a statement on why they're making such dramatic changes? It seems like the lesson to internalize from mlugg is not "switch to Rust"

Interesting. When I thought of Zig, I thought of Bun. In my mind it was the flagship application for that language. Is there another? I wonder how the Zig team feels about this. To me it seems like Rust has definitively won now.

the days are not far when golang will be ported to rust.

>*No `tokio`, `rayon`, `hyper`, `async-trait`, `futures`.* No `std::fs`,

I'm not a rust dev but even I kind of notice that tokio is kind of shunned in most projects. Why is that? Is it just bad or what?

Here we go again ...

Company A buys company B. A's management decrees the henceforth B's aqcuihired team must comply with company A's standards.

Second system effect kicks in. Bugs multiply.

Half of original company B devs leave.

I'm investigating whether future projects should revert to using Deno.

instead of writing it once in C++

what a win

you can use both zig and rust in a single project, duh

it will make it more portable.

People are asking why they would switch from zig to rust. I wonder the opposite: why would anyone would use zig over rust?

Makes sense on merit. There really isn’t room for Zig when Rust exists, is more ergonomic, and also safe.

hahaha eat your heart out "don't port it to rust" gang

I fully support this decision
