abstract class AsyncBase extends AnyRef

A base class for the async macro. Subclasses must provide:

- Concrete types for a given future system - Tree manipulations to create and complete the equivalent of Future and Promise in that system. - The async macro declaration itself, and a forwarder for the macro implementation. (The latter is temporarily needed to workaround bug SI-6650 in the macro system)

The default implementation, scala.async.Async, binds the macro to scala.concurrent._.

    A call to await must be nested in an enclosing async block.

    A call to await must be nested in an enclosing async block.

    A call to await does not block the current thread, rather it is a delimiter used by the enclosing async macro. Code following the await call is executed asynchronously, when the argument of await has been completed.

    T

    the type of that value.

    awaitable

    the future from which a value is awaited.

    returns

    the value.
