From: Jeffrey Czyz Date: Tue, 6 Aug 2024 22:17:52 +0000 (-0500) Subject: Make payment_hash optional in Event::PaymentFailed X-Git-Tag: v0.0.124-beta~12^2~6 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=14153edeed100bc311bd1eca95ac4717c4d6583c;p=rust-lightning Make payment_hash optional in Event::PaymentFailed When abandoning a BOLT12 payment before a Bolt12Invoice is received, an Event::InvoiceRequestFailed is generated and the abandonment reason is lost. Make payment_hash optional in Event::PaymentFailed so that Event::InvoiceRequestFailed can be removed in favor of it. --- diff --git a/lightning/src/events/mod.rs b/lightning/src/events/mod.rs index 393acbc02..a94d6c118 100644 --- a/lightning/src/events/mod.rs +++ b/lightning/src/events/mod.rs @@ -879,10 +879,12 @@ pub enum Event { /// /// [`ChannelManager::send_payment`]: crate::ln::channelmanager::ChannelManager::send_payment payment_id: PaymentId, - /// The hash that was given to [`ChannelManager::send_payment`]. + /// The hash that was given to [`ChannelManager::send_payment`]. `None` if the payment failed + /// before receiving an invoice when paying a BOLT12 [`Offer`]. /// /// [`ChannelManager::send_payment`]: crate::ln::channelmanager::ChannelManager::send_payment - payment_hash: PaymentHash, + /// [`Offer`]: crate::offers::offer::Offer + payment_hash: Option, /// The reason the payment failed.
