You can also use the typed-arena crate[0] or roll your own if you're feeling like cracking open unsafe. [0] https://crates.io/crates/typed-arena https://crates

  Typed-arena is a bit limited, because all the allocated values must be of the same type. bumpalo[0] removes that restriction, but it also doesn't run destructors, which can lead to memory and other resource leaks. Another worry I have with bumpalo is that I don't think it's been reviewed thoroughly for unsoundness. Still, bumpalo has been used to great effect in dodrio[1], a React-like library for Rust with really good performance.
