warning: unused `Result` that must be used --> src/main.rs:127:5 | 127 | write!(writer, "{}", n_retrogrades); | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: this `Result` may be an `Err` variant, which should be handled = note: `#[warn(unused_must_use)]` on by default = note: this warning originates in the macro `write` (in Nightly builds, run with -Z macro-backtrace for more info)
