Issue #21695 has been updated by matz (Yukihiro Matsumoto). I am interested. What kind of API do you need? Since bare memory allocation could break the whole app (leads to DoS), it's not that easy to disclose general purpose memory allocation (that's the reason YJIT, RJIT etc. has their own allocators), but there might be the way to satisfy your version of performance improvement. Matz. ---------------------------------------- Feature #21695: Optimizing Ruby performance with Ruby itself instead of Rust https://bugs.ruby-lang.org/issues/21695#change-115238 * Author: fredlinhares (Frederico Linhares) * Status: Open ---------------------------------------- I am using ERB on top of C for a game I am making now. We can use the tool to improve the productivity, memory safety, and runtime speed for Ruby. It can also replace a Rust JIT compiler for better results. The only problem is that it requires some level of manual memory management, while Rust does it all for you. If I demonstrate that it is better than Rust in practice, would you be willing to incorporate it into the Ruby language? I want to know because making it more generic will require more effort from me; if you are not interested, I won’t make the tool public. -- https://bugs.ruby-lang.org/
