6 |     let headers = [Header{value: &[]}; 128];
  |         ^^^^^^^ help: if this is intentional, prefix it with an underscore: `_headers`

  = note: `#[warn(unused_variables)]` on by default

error[E0277]: the trait bound `Header<'_>: Copy` is not satisfied
 --> /home/runner/work/glacier/glacier/ices/80371.rs:6:19
  |
6 |     let headers = [Header{value: &[]}; 128];
  |                   ^^^^^^^^^^^^^^^^^^^^^^^^^ the trait `Copy` is not implemented for `Header<'_>`
  |
  = note: the `Copy` trait is required because the repeated element will be copied

error: aborting due to previous error; 1 warning emitted
