Imo, the bigger downside of using Pony is that its garbage collected.
Perfect memory safety (outside of ffi ofc) is implemented in a lot of languages. What makes Rust unique is that it gives you reliable memory safety without requiring a garbage collector.

Hey, I am working on building my first big game and starting my indie studio. Would love to chat about why you chose to build a custom engine. I am also debating if I should build a custom engine.

I think your DMs are not open. By default bsky only allows the people you follow to DM you. Since you don't follow me I can't DM you.
There is a setting in the chat tab to allow anyone to DM you.

If the LLM is trained well on the language you are trying to generate, as long as you know how to communicate technical specifications you are good imo.

I kinda disagree that there is much skill involved here.
I could never get LLMs to produce usable code for Rust but I recently started working on a React project and the difference is night and day.
It can produce working things in react without anything changing about how I prompt it.

The features that are missing from enums are because it needs to support both enums that hold data and those that don't.

Functions to iterate over the variants or convert from int to the variant can only be implemented for enums that don't hold any data.

So rust does not implement them at all.

I agree that Rust's enums are not as powerful as they can be. I for one would like to be able to iterate over the elements of an enum without having to derive anything.

For a simple enum like Clex you can just transmute it as shown below. Assuming we are sure that the value is a valid variant.

Rust supports an easy way to do this.
play.rust-lang.org?version=stab...
The code below just works

You can also use the new crabtime crate. I haven't used it before but it looks very useful for things like this.

Only for loops are disallowed in a const context. You can still use a while loop or a loop loop.

Have you tried installing rustup on the docker image?

Where are you based? The startup that I work at is looking for someone experienced in #Rust and graphics programming in San Fransisco or willing to move to San Fransisco.

DM me if you are interested.

I said it was guaranteed because rust is trying to guarantee it. If an optimization is possible and does not happen it is usually treated as a bug in the compiler. There has been a fair bit of work on optimising the MIR to reduce the burden on LLVM to figure out the optimizations for the abstraction
