When running this example with no cargo features enabled, the compiler
warns on 1.89:
error: struct `Error` is never constructed
--> examples/error.rs:11:12
|
11 | pub struct Error;
| ^^^^^
|
= note: `-D dead-code` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(dead_code)]`
Thus use the error in the main function to avoid this warning.
