error[E0502]: cannot borrow `heap` as immutable because it is also borrowed as mutable
--> $DIR/issue-47646.rs:22:30
|
LL | let borrow = heap.peek_mut();
| ---- mutable borrow occurs here
LL |
LL | match (borrow, ()) {
| ------------ a temporary with access to the mutable borrow is created here ...
LL | (Some(_), ()) => {
LL | println!("{:?}", heap); //~ ERROR cannot borrow `heap` as immutable
| ^^^^ immutable borrow occurs here
...
LL | };
| - ... and the mutable borrow might be used here, when that temporary is dropped and runs the destructor for type `(std::option::Option<std::collections::binary_heap::PeekMut<'_, i32>>, ())`
error: aborting due to previous error
