Rust, tui, mini-vi/mini-emacs?

[mbrubeck]

I'm not sure how close these are to what you're looking for, but here are some recent TUI text editors written in Rust:

• GitHub - dpc/breeze: An experimental, kakoune-inspired CLI-centric text/code editor with |-shaped cursor (in Rust)
• Hecto: Build your own text editor in Rust – Philipp Flenker – Engineering Manager
• GitHub - curlpipe/ox: An independent Rust text editor that runs in your terminal!
