Rust REPL console

REPL console is an interactive read-eval-print-loop environment for prototyping and testing your Rust code. This handy tool is a notebook, a calculator, and a Rust interpreter all in one.

Implemented on top of the evcxr_repl utility, Rust REPL provides syntax highlighting and completion for the code lines you type. It also shows a pane with the list of variables, functions, and structures currently in use.

You can access the REPL console from the context menu (Rust | Rust REPL), run it from the main menu (Tools | Rust | Rust REPL), or look it up in the Search Everywhere dialog (double ).

Find below an example of how the REPL console can be used to draft a simple program in Rust:
