Calling Functions

After defining a function and registering it with a Dispatch endpoint, the next step is to dispatch a call.

Given a Dispatch function that converts an integer to a string:

stringify := dispatch.Func("stringify", func (ctx context.Context, input int) (string, error) {
    return strconv.Itoa(input), nil
})

A function call can be dispatched using the Dispatch method, which accepts an input argument.

For example, to dispatch a stringify(11) call:

id, err := stringify.Dispatch(context.Background(), 11)

This submits a function call to the Dispatch cloud service, which coordinates the execution of the function.

The Dispatch method returns a globally unique identifier for the function call, for observability purposes. If the function call could not be dispatched, an error is instead returned.
