External method to call the event action **IMPORTANT**: Dont forget to add it to the register in the 'Init' function in the ev_register package if you want to be able to call this event with recalled data # External because we cant do generic class methods This function takes an EVEvent and calls the 'Do' method of the action returns EVEventExecError: - ActionError: error from the action : check for nil to see if the action was successful( nil means success ) - StreamError: error from streaming the event : check for nil to see if the event was streamed successfully - StoreError: error from storing the event to the database : check for nil to see if the event was stored successfully.

intialize the package with the database connection and the event names see the EVEventNames map in this package for an example.

SetDBCONN sets the global variable DBCONN to the database connection.

EXAMPLE FUNCTION AND DATA WE WANT TO RUN AS AN EVENT Some Data Types, Context Types, and Functions we dont want to just run our function 'UpdateATestDataType' willy nilly, we want to dispatch is as an event, with its data, and its context, and its success or failure, and log it, or queue it, or replay it , etc We want to package these into an actionable event! */.

The action event class EVEvent Class associates types and interfaces are: - UnixTimeMilliseconds - EVTypes_int - IEVAction (interface).

NoMetaData: keep some empty struct around for the places where you dont need events to have meta data we've included 'NoMetaData' in this package.

Here is an example of how to make an IEVAction for the event class # Make a struct that implements the IEVAction interface Make a method called 'Do' that takes the data type of the event and returns an error This is where you put the function you want to run as an event!.

The action interface The action interface is a generic interface that can be implemented by any struct The struct must have a method called "Do" that takes one argument of any type and returns an error.
