I’m trying to write to a file but starting from a certain position. I’ve tried to use
write_at() but it doesn’t work.
- The file is overwritten anyway, so what’s the point?
- It’s a UNIX-only API, and I would like to let people use my program on for example Windows and macOS.
let mut file = OpenOptions::new().write(true).open("example.txt")?; file.seek(SeekFrom::Start(1234))?; file.write_all(b"foobar")?;
