source · pub fn membarrier_query() -> MembarrierQueryExpand description
membarrier(MEMBARRIER_CMD_QUERY, 0, 0)—Query the supported membarrier
commands.
This function doesn’t return a Result because it always succeeds; if the
underlying OS doesn’t support the membarrier syscall, it returns an empty
MembarrierQuery value.
