Type Alias Result 

pub type Result<T, E = Error> = Result<T, E>;

The top-level result type for dealing with fallible operations. The errors tend to be fail-stop, and nested results are used in cases where the outer fail-stop error can have try ? used on it, exposing the inner operation that is expected to fail under normal operation. The philosophy behind this is detailed on the sled blog.

    Ok(T),
    Err(E),
}
