As a C programmer who uses memory arenas quite frequently can you expand on what you know about Rust’s current or future support for such a feature?

I’d like to start writing new projects in Rust and I’d like to continue to use this approach to memory management!

You can of course use arenas in Rust just like in C. I think the parent was talking about support for using arenas as the memory for stuff like built-in containers (dynamic arrays, hash maps, etc.):

Thank you! Yeah, something like bumpalo would work just fine right now but for the future this is a great interface:

https://docs.rs/bumpalo/latest/bumpalo/#nightly-rust-allocat...

  use bumpalo::Bump;
  
  let bump = Bump::new();
  
  let mut v = Vec::new_in(&bump);
  v.push(0);
  v.push(1);
  v.push(2);
