Trait SubError 

pub trait SubError<T> {
    // Required method
    fn to_super_error(self) -> T;
}

Represents an error that can be upcasted to a different error type.

If type A implements SubError<B>, that means that B contains all variants that A has, and as such A can be converted to B.

This trait powers the #[throws] and define_error!() macros. It’s implemented by all error types they generate and required for suberrors declared with the break keyword.
