Module Statx.MaskSource

The mask flags are used to tell the kernel which fields the statx invocation is interested in. You may wish to use Mask.check on the returned Statx.t to verify the field has actually been filled in with a sensible value first. In general, the kernel never refused values specified in the mask, but may choose to not set the mask in the returned buffer from statx.
