Fix issue from:
#147455 (comment)

old code opts.write(true) on Windows requests GENERIC_WRITE access, replace with opts.access_mode(c::FILE_WRITE_ATTRIBUTES) to get minimal permission.

Sorry. The bug was my mistake. set_times actually works with directories on nightly 57d2fb136 2026-02-01 (before the fix).

What I did was:

  • times.set_created(created); instead of
  • times = times.set_created(created);, which returns Self to be assigned later.

Maybe #[must_use] would prevent such bugs with FileTimes::set_created.

could you please confirm the new nightly also work?
if there was no issues, we can keep the change.
there is a unit test, I assume it works as before.

The change looks good to me regardless. Using the minimum necessary permissions is going to work in more situations and it's documented that FILE_WRITE_ATTRIBUTES is all that's needed. https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfiletime
