option

A generic Option<T> for representing an optional value without needing a zero/null value for T (backed internally by a 0- or 1-element List<T>). some/none construction, isSome/isNone checks, unwrap/unwrapOr, and map/andThen/orElse combinators.

Some none

        let missing: Option<Int64> = Option<Int64>::none();

        println("found.isSome() = " + found.isSome().toString());
        println("found.unwrap() = " + found.unwrap().toString());
        println("missing.unwrapOr(-1) = " + missing.unwrapOr(-1).toString());
