    default <X extends Throwable>
    Try<T>
    Try.recoverWith(Class<X> exceptionType, Function<? super X, Try<? extends T>> f)
    Returns this, if this is a Success or this is a Failure and the cause is not assignable from cause.getClass().
    default Try<T>
    Try.recoverWith(Function<? super Throwable, ? extends Try<? extends T>> f)
    Returns this, if this is a Success, otherwise tries to recover the exception of the failure with f, i.e. calling f.apply(cause.getCause()).
    static <T> Try<Seq<T>>
    Try.sequence(Iterable<? extends Try<? extends T>> values)
    Reduces many Trys into a single Try by transforming an Iterable<Try<? extends T>> into a Try<Seq<T>>.
    default <U> U
    Try.transform(Function<? super Try<T>, ? extends U> f)
    Transforms this Try.
    static <T,U> Try<Seq<U>>
    Try.traverse(Iterable<? extends T> values, Function<? super T, ? extends Try<? extends U>> mapper)
    Maps the values of an iterable to a sequence of mapped values into a single Try by transforming an Iterable<? extends T> into a Try<Seq<U>>.
