Using Seek::seek is slightly clumsy because of the need to write (or import) std::io::SeekFrom to get at SeekStart. C already has rewind (although with broken error handling); we should have it too.
I'm motivated to do this because I've just found myself copy-pasting my 5-line extension trait between projects.
That the example ends up using OpenOptions makes this look like a niche use case, but it is very common to rewind temporary files. tempfile isn't available for use in this example or it would have looked shorter and more natural.
If this gets a positive reception I will open a tracking issue and update the feature gate.
