    async(Cont<T> cont, T value)
    Returns a Runnable that, when executed, invokes the given continuation with the provided constant value.
    void
    bind(T value)
    Invoked when the asynchronous operation completes with a value.
    static <X, T> Cont<X>
    constant(Cont<T> cont, T value)
    Returns a Continuation that, when completed successfully, completes the given continuation with the provided constant value; and when failed with an error, fails the given continuation with the error.
    static <T> Cont<T>
    ignore()
    Returns a Cont continuation that, when completed successfully, does nothing; and when failed with an exception, throws the exception.
    static boolean
    isNonFatal(Throwable throwable)
    Returns true if throwable is a recoverable exception; returns false if throwable cannot be recovered from.
    void
    trap(Throwable error)
