A Modern Editor Built in Rust
summary
XIeditor is a high‑performance text editor implemented primarily in Rust, claiming 10,000 lines of Rust with 0 uses of unsafe, plus a Mac front end of 1,200 lines of Swift and 27 contributors. It loads a 380 megabyte file in about a second, sustains 60 fps scrolling, uses rope trees for log‑time edits, incremental word‑wrap touching 140 bytes in 0.01 ms, a Unicode line‑breaker 3× faster than ICU, and a JSON‑RPC microservice plugin model that demonstrably works.
