 834          *
 835          * `phantom_route_hints` parameter:
 836          * Contains channel info for all nodes participating in the phantom invoice
 837          * Entries are retrieved from a call to [`ChannelManager::get_phantom_route_hints`] on each
 838          * participating node

 840          * updated when a channel becomes disabled or closes
 841          * Note that the route hints generated from `phantom_route_hints` will be limited to a maximum
 842          * of 3 hints to ensure that the invoice can be scanned in a QR code. These hints are selected

 845          * desired, but note that some nodes will be trimmed if more than 3 nodes are provided.
 846          *

 848          *
 849          * `payment_hash` can be specified if you have a specific need for a custom payment hash (see the difference

 851          * If `None` is provided for `payment_hash`, then one will be created.
 852          *
 853          * `invoice_expiry_delta_secs` describes the number of seconds that the invoice is valid for
 854          * in excess of the current time.
 855          *
 856          * `duration_since_epoch` is the current time since epoch in seconds.

 858          * Note that the provided `keys_manager`'s `NodeSigner` implementation must support phantom
