    // Required method
    fn into_validated(self) -> Validated<HCons<T, HNil>, E>;
}

Required Methods

fn into_validated(self) -> Validated<HCons<T, HNil>, E>

Consumes the current Result into a Validated so that we can begin chaining

let r1: Result<String, i32> = Err(32);
let v = r1.into_validated();
assert!(v.is_err());
