error[E0382]: assign to part of moved value: `self.0`
 --> /home/runner/work/glacier/glacier/ices/91816.rs:6:9
  |
5 |         let _arr = self.0;
  |                    ------ value moved here
6 |         self.0[0].1 = value; //~ move
  |         ^^^^^^^^^^^ value partially assigned here after move
  |
  = note: move occurs because `self.0` has type `[(K, V); 1]`, which does not implement the `Copy` trait

error: aborting due to 3 previous errors
