pub(crate) struct DanglingPointers;
Expand description
FIXME: false negatives (i.e. the lint is not emitted when it should be)
- Ways to get a temporary that are not recognized:
owning_temporary.field
owning_temporary[index]
- No checks for ref-to-ptr conversions:
&raw [mut] temporary
&temporary as *(const|mut) _
ptr::from_ref(&temporary)
and friends
