error[E0509]: cannot move out of type `S`, which implements the `Drop` trait
  --> $DIR/overlapping_spans.rs:20:11
   |
LL |     match (S {f:"foo".to_string()}) {
   |           ^^^^^^^^^^^^^^^^^^^^^^^^^ cannot move out of here
LL |         S {f:_s} => {} //~ ERROR cannot move out
   |              -- data moved here
   |
note: move occurs because `_s` has type `std::string::String`, which does not implement the `Copy` trait
