Properties:

• public abstract Error? exception { get; }
  Checks the exception that have been set. I.e. if the computation has thrown the exception it should be set here and the wait, wait_until and wait_async should throw FutureError.EXCEPTION.
• public abstract bool ready { get; }
  Checks if value is ready. If it is calls to wait and wait_until will not block and value is returned immediately.
• public virtual G value { get; }
  The value associated with Future. If value is not ready getting value will block until value is ready.

Delegates:

• public delegate Future<A> FlatMapFunc<A,G> (G value)
• public delegate unowned A LightMapFunc<A,G> (G value)
• public delegate A MapFunc<A,G> (G value)
• public delegate C ZipFunc<A,B,C> (A a, B b)

Methods:

• public virtual Future<A> flat_map<A> (owned FlatMapFunc<A,G> func)
  Maps a future value to another future value which is returned (call does not block).
• public virtual Future<A> light_map<A> (owned LightMapFunc<A,G> func)
  Maps a future value to another value by a function and returns the another value in future.
• public virtual Future<A> light_map_broken<A> (LightMapFunc<A,G> func)
• public virtual Future<A> map<A> (owned MapFunc<A,G> func)
  Maps a future value to another value by a function and returns the another value in future.
• public abstract unowned G wait () throws FutureError
  Waits until the value is ready.
• public abstract async unowned G wait_async () throws FutureError
  Reschedules the callback until the value is available.
• public abstract bool wait_until (int64 end_time, out unowned G value = null) throws FutureError
  Waits until the value is ready or deadline have passed.
• public virtual Future<B> zip<A,B> (owned ZipFunc<G,A,B> zip_func, Future<A> second)
  Combines values of two futures using a function returning the combined value in future (call does not block).
