error[E0308]: mismatched types
 --> /home/runner/work/glacier/glacier/ices/86082.rs:2:5

1 | fn main() {
  |           - expected `()` because of default return type
2 |     option_env!("\0")
  |     ^^^^^^^^^^^^^^^^^ expected `()`, found enum `Option`
  |
  = note: expected unit type `()`
                  found enum `Option<&'static str>`
  = note: this error originates in the macro `option_env` (in Nightly builds, run with -Z macro-backtrace for more info)

error: aborting due to previous error
