Cool! I assume TRUST stands for "Turbo Rust"? If yes, maybe it would be worth mentioning that in the readme. I doubt that Embarcadero Technologies (the current owners of the Delphi and C++ Builder IDEs, and probably also the owners of other former Borland trademarks) would mind - but then again, it doesn't hurt to stay on the safe side...
I haven't felt a lot of desire to code in Rust but I do now! Absolutely applaud this project - it's completely tugged on the retro nostalgia strings for my Turbo Pascal days. Also one of the reasons I enjoy the previously HN featured Microsoft Edit project immensely - https://github.com/microsoft/edit. Thank you OP
Honestly the experience looks pretty nice. Which is crazy to say for such an old style of program but I kind of like it. Perhaps just nostalgia for a time I never got your experience.
A year or so ago I spent half a day writing some Rust on an actual DEC glass teletype (VT520) connected to a Debian box. I used vim and shell job control (^Z, jobs, fg, etc.) to switch between tooling and a persistent text editor. It made me feel things.
