pub fn detect(header: &[u8], footer: &[u8]) -> ContainerFormatExpand description
Sniff the container format from a disk image’s header (its first bytes,
ideally ≥512) and footer (its last 512 bytes — VHD’s conectix cookie and
DMG’s koly trailer live at the end of the file).
Returns ContainerFormat::Raw when no wrapper magic is present (a bare
MBR/GPT/APM disk).
