Provide io::Seek::rewind 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. |
