As a vim user I can attest to this. Rust tooling is better for me than any other language I have ever used. Only thing I ever wish for is a REPL, which is a big ask for a language like Rust.

While it's not official, rusti[1] by murarth is a functioning Rust REPL. IIRC, it's used to drive the Rust Playground[2] (don't quote me on that).

Rusti isn't 'there yet,' unfortunately. It is forced to recompile the entire project for every line entered. Aa far as I know I also can't do things like set 'breakpoints' that will pause execution and drop me into the REPL, like Ruby's binding.pry.

This is a very hard feature for compiled languages, its just a con of this execution model (which is has a lot of pros).

I believe the playground is just a well-sandboxed Rust compiler. It doesn't have any of the fancy features of a REPL, such as allowing you to refer to the state of prior runs.
