// This is testing how the diagnostic from issue #54556 behaves when
|
||
|
|
// the destructor code is attached to a place held in a field of the
|
||
|
|
// temporary being dropped.
|
||
|
|
//
|
||
|
|
// Eventually it would be nice if the diagnostic would actually report
|
||
|
|
// that specific place and its type that implements the `Drop` trait.
|
||
|
|
// But for the short term, it is acceptable to just print out the
|
||
|
|
// whole type of the temporary.
