) -> Result<(PaymentHash, RecipientOnionFields, RouteParameters), ()>
Expand description
Builds the necessary parameters to pay or pre-flight probe the given zero-amount
Bolt11Invoice
using ChannelManager::send_payment
or
ChannelManager::send_preflight_probes
.
Prior to paying, you must ensure that the Bolt11Invoice::payment_hash
is unique and the
same PaymentHash
has never been paid before.
Will always succeed unless the invoice has an amount specified, in which case
payment_parameters_from_invoice
should be used.
