Jeffrey Czyz	d666eb6700	Invoice request building tests ... Tests for checking invoice_request message semantics when building as defined by BOLT 12.	2022-12-09 13:28:26 -06:00
Jeffrey Czyz	13ba7cc523	Builder for creating invoice requests ... Add a builder for creating invoice requests for an offer given a payer_id. Other settings may be optional depending on the offer and duplicative settings will override previous settings. Building produces a semantically valid `invoice_request` message for the offer, which then can be signed for the payer_id.	2022-12-09 08:53:46 -06:00
Jeffrey Czyz	59a7bd29fe	Invoice request raw byte encoding and decoding ... When reading an offer, an `invoice_request` message is sent over the wire. Implement Writeable for encoding the message and TryFrom for decoding it by defining in terms of TLV streams. These streams represent content for the payer metadata (0), reflected `offer` (1-79), `invoice_request` (80-159), and signature (240).	2022-12-09 08:53:46 -06:00
Jeffrey Czyz	a7adc7602a	Merkle root hash computation ... Offers uses a merkle root hash construction for signature calculation and verification. Add a submodule implementing this so that it can be used when parsing and signing invoice_request and invoice messages.	2022-12-09 08:53:45 -06:00
