otp VS rust

Modern type system over BEAM sounds great but unfortunately OTP is still not 100% supported https://github.com/gleam-lang/otp?tab=readme-ov-file#limitat...

They seem to have rewritten/wrapped OTP, but it's not production ready. https://github.com/gleam-lang/otp

YMMV, but a BEAM language without OTP severely limits its appeal and usability.

Looks like it is an external library[^1]. Readme states it is experimental and lists some limitations.

We have a fully type safe and OTP compatible implementation of actors and supervisors here https://github.com/gleam-lang/otp

No primitives as it's not possible to have them when compiling to JavaScript, but we do have them as types and functions in the OTP library https://github.com/gleam-lang/otp

On the advice of u/WrongJudgment6 I'm reading the Gleam OTP tests. But I can't compile, and hence can't test, the code. (I'd like to do that so I can tweak the tests to do my own experiments.) Whenever I try I get an error like this:

And docs at https://hexdocs.pm/gleam_otp/

We have a fully type safe and Erlang compatible OTP library! It is used in production today.

https://github.com/gleam-lang/otp

It is not a wrapper around gen_server etc, but instead it is a full implementation from the ground up using a very small core. This was done because:

a) Erlang OTP cannot be typed, we need different abstractions are designed with types in mind

b) We want to be confident that our abstractions are powerful enough to build something like OTP, rather than cheating by relying on type casts.

I'm very happy with how Gleam OTP is going, but it is not the focus now that an initial version is out. Tooling and documentation is more important at the moment.

If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Here's an example of someone citing a disagreement between CRT and shell32:

This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:

Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

    #include 

> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.

Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Almost fixed the compiler: https://github.com/rust-lang/rust/pull/123325

Rust: A secure, efficient, and modern programming language (omitting ten thousand words). You can simply follow the installation instructions provided on the official website.

Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.

To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/

We strongly believe in Rust as a powerful language for building production-grade software, especially for systems like ours that run alongside Kubernetes.

The above Assert<{N % 2 == 1}> requires #![feature(generic_const_exprs)] and the nightly toolchain. See https://github.com/rust-lang/rust/issues/76560 for more info.
