Description
The following functions in the crate are affected:
IdMap::clone_from
The clone_from implementation for IdMap drops the values present in the
map and then begins cloning values from the other map. If a .clone() call
pancics, then the afformentioned dropped elements can be freed again.
get_or_insert
get_or_insert reserves space for a value, before calling the user provided
insertion function f. If the function f panics then uninitialized or
previously freed memory can be dropped.
remove_set
When removing a set of elements, ptr::drop_in_place is called on each of the
element to be removed. If the Drop impl of one of these elements panics then
the previously dropped elements can be dropped again.
