pub fn up_iter<'a>(data: &'a [u8], bbheader: &Bbheader) -> UpIter<'a> ⓘExpand description
Build an appropriate user-packet iterator for the given BBHEADER.
Returns either an NM or HEM iterator depending on the detected mode.
The caller must handle SYNCD alignment before calling this — typically
by skipping syncd / 8 bytes at the start of the data field.
