pub fn new(
payer: P,
router: R,
scorer: S,
logger: L,
event_handler: E,
retry_attempts: RetryAttempts
) -> Self
Creates an invoice payer that retries failed payment paths.
Will forward any Event::PaymentPathFailed events to the decorated event_handler once
retry_attempts has been exceeded for a given Invoice.
Pays the given Invoice, caching it for later use in case a retry is needed.
You should ensure that the invoice.payment_hash() is unique and the same payment_hash has
never been paid before. Because InvoicePayer is stateless no effort is made to do so
for you.
pub fn pay_zero_value_invoice(
&self,
invoice: &Invoice,
amount_msats: u64
) -> Result<PaymentId, PaymentError>
pub fn pay_zero_value_invoice(
&self,
invoice: &Invoice,
amount_msats: u64
) -> Result<PaymentId, PaymentError>
Pays the given zero-value Invoice using the given amount, caching it for later use in
case a retry is needed.
You should ensure that the invoice.payment_hash() is unique and the same payment_hash has
never been paid before. Because InvoicePayer is stateless no effort is made to do so
for you.
Removes the payment cached by the given payment hash.
Should be called once a payment has failed or succeeded if not using InvoicePayer as an
EventHandler. Otherwise, calling this method is unnecessary.
