Functions

func MppPayment 

func MppPayment(spw SendPayPartWaiter, payreq string, channel string, bolt11 *glightning.DecodedBolt11) (string, error)

MppPayment splits the payment in parts and waits for the payments to finish. We split in 10 parts as this will always result in a set of payments that dont have a "rest" and are all of the exact same size. They match the total amount that we want to transfer. As we only send over a direct channel to a direct peer we also dont need to optimize on a small number of subpayments.
