+ * Attempts to forward an intercepted HTLC over the provided channel id and with the provided
+ * amount to forward. Should only be called in response to an [`HTLCIntercepted`] event.
+ *
+ * Intercepted HTLCs can be useful for Lightning Service Providers (LSPs) to open a just-in-time
+ * channel to a receiving node if the node lacks sufficient inbound liquidity.
+ *
+ * To make use of intercepted HTLCs, set [`UserConfig::accept_intercept_htlcs`] and use
+ * [`ChannelManager::get_intercept_scid`] to generate short channel id(s) to put in the
+ * receiver's invoice route hints. These route hints will signal to LDK to generate an
+ * [`HTLCIntercepted`] event when it receives the forwarded HTLC, and this method or
+ * [`ChannelManager::fail_intercepted_htlc`] MUST be called in response to the event.
+ *
+ * Note that LDK does not enforce fee requirements in `amt_to_forward_msat`, and will not stop
+ * you from forwarding more than you received.
+ *
+ * Errors if the event was not handled in time, in which case the HTLC was automatically failed
+ * backwards.
