Struct DanglingPointers

pub(crate) struct DanglingPointers;

FIXME: false negatives (i.e. the lint is not emitted when it should be)

1. Method calls that are not checked for:
   • temporary_unsafe_cell.get()
   • temporary_sync_unsafe_cell.get()
2. Ways to get a temporary that are not recognized:
   • owning_temporary.field
   • owning_temporary[index]
3. No checks for ref-to-ptr conversions:
   • &raw [mut] temporary
   • &temporary as *(const|mut) _
   • ptr::from_ref(&temporary) and friends

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
