func Main ¶

func Main(ctx context.Context, args []string, stderr io.Writer) (err error)

Main is a main function for the external processor exposed for allowing users to build their own external processor.

* ctx is the context for the external processor. * args are the command line arguments passed to the external processor without the program name. * stderr is the writer to use for standard error where the external processor will output logs.

This returns an error if the external processor fails to start, or nil otherwise. When the `ctx` is canceled, the function will return nil.
