Why do we treat no-route differently from all-routes-failed-immediately?

Not sure... was just trying to maintain the same behavior. ChannelManager never gets called in this case, so maybe there's no need to update the payment storage? (cc: @valentinewallace)

Hm yeah I don’t think either would make sense to put in PaymentStorage. Don’t recall my exact reasoning tho.

Yea, I think don't bother to store them? I'm not even sure if we need to store outbound payments anyway at this point?

list_payments currently allows you to see whether an outbound payment is pending vs completed/failed, due to storing them here. Could be exposed from ChannelManager instead tho

Ah, yeah and right now neither inbound nor outbound payments are persisted in the sample. They're just used in list_payments. I can drop them entirely. Just want to note that it seems independent of the PR. Happy to do it here in a follow-up.

Fair, lets do it in a followup and land this for now.

Hmm... so won't ChannelManager eventually remove the payments after they've been fulfilled? The sample would still needs to keep track of these, right? The idea of list_payments is basically a transaction log, IIUC.

I second this, though payments are currently not persisted to disk in the sample. So IMO inbound/outbound tracking shouldn’t be removed

Hmmmmmm, we really need to get InvoicePayer to support spontaneous payments eventually.

Yeah, just opened issue lightningdevkit/rust-lightning#1156. Happy to take it on.
