Trait PaymentObserver 

pub trait PaymentObserver: Send + Sync {
    // Required method
    fn before_send<'life0, 'async_trait>(
        &'life0 self,
        payments: Vec<ProvisionalPayment>,
    ) -> Pin<Box<dyn Future<Output = Result<(), PaymentObserverError>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

This interface is used to observe outgoing payments before Lightning, Spark and onchain Bitcoin payments. If the implementation returns an error, the payment is cancelled.

Required Methods

fn before_send<'life0, 'async_trait>( &'life0 self, payments: Vec<ProvisionalPayment>, ) -> Pin<Box<dyn Future<Output = Result<(), PaymentObserverError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Called before Lightning, Spark or onchain Bitcoin payments are made
