Interface NeoQueue.IAsyncErrFirstCb<T>

All Known Implementing Classes:
NeoQueue.AsyncCallback
Enclosing class:
NeoQueue<T,V>
public static interface NeoQueue.IAsyncErrFirstCb<T>
Error-first continuation used by NeoQueue.ITaskHandler. Like Asyncc.IAsyncCallback but with Object as the error type because the pre-existing public API of NeoQueue pre-dates the typed-error parameter.

The conventional parameter name in user code is c, short for continuation.

Since:
0.2.4 (success / fail defaults added)
