alt Hacker NewsI would recommend using the ropey crate for easy performance gains. A string buffer is quick to implement but you will hit a wall as soon as you need to edit large files.

Unmentioned in the post, but I have since switched to a third-party rope library (crop, not ropey). At some point I'd like to implement one myself, but for now this does the job.
It's not that bad. You need really large files to notice. The largest realistic file I'll ever touch - sqlite3 amalgamation with 270k lines and 9.1 kB - still takes only 6 ms to memmove it on my poor laptop. Any regular up-to 10k lines file is memmoved in order of microseconds.
