How do I do it for seek_mut()?

[rockit-ba]

like this:

use memmap2::MmapMut;

let mut mmap = MmapMut::open_path(file_path, memmap2::Protection::ReadWrite)?;
mmap.seek_mut(10)?;

Is not clear what you mean by seek_mut. You also seem to refer to the API of another crate as this crate does have an open_path method or a Protection enum.

Do you mean how to turn MmapMut into an instance of Seek? If so, then the answer is to wrap it in a Cursor, e.g.

let mmap = MmapMut::open(file)?;
let mut cursor = Cursor::new(mmap);
cursor.seek(SeekFrom::Start(10))?;
