+/// Note that we use block header time to time-out pending inbound payments (with some margin
+/// to compensate for the inaccuracy of block header timestamps). Thus, in practice we will
+/// accept a payment and generate a [`PaymentReceived`] event for some time after the expiry.
+/// If you need exact expiry semantics, you should enforce them upon receipt of
+/// [`PaymentReceived`].
+///
+/// Pending inbound payments are stored in memory and in serialized versions of this
+/// [`ChannelManager`]. If potentially unbounded numbers of inbound payments may exist and
+/// space is limited, you may wish to rate-limit inbound payment creation.
+///
+/// May panic if `invoice_expiry_delta_secs` is greater than one year.
+///
+/// Note that invoices generated for inbound payments should have their `min_final_cltv_expiry`
+/// set to at least [`MIN_FINAL_CLTV_EXPIRY`].
+///
+/// [`create_inbound_payment`]: Self::create_inbound_payment
+/// [`PaymentReceived`]: events::Event::PaymentReceived
