-/**
- * A trait defining behavior of an [`Invoice`] payer.
- *
- * While the behavior of [`InvoicePayer`] provides idempotency of duplicate `send_*payment` calls
- * with the same [`PaymentHash`], it is up to the `Payer` to provide idempotency across restarts.
- *
- * [`ChannelManager`] provides idempotency for duplicate payments with the same [`PaymentId`].
- *
- * In order to trivially ensure idempotency for payments, the default `Payer` implementation
- * reuses the [`PaymentHash`] bytes as the [`PaymentId`]. Custom implementations wishing to
- * provide payment idempotency with a different idempotency key (i.e. [`PaymentId`]) should map
- * the [`Invoice`] or spontaneous payment target pubkey to their own idempotency key.
- *
- * [`ChannelManager`]: lightning::ln::channelmanager::ChannelManager
