The only way to know if an invoice is AMP, Keysend, etc is to look at its shape/characteristics. This commit adds a couple of helper functions to encapsulate the logic of these checks. If all these types cannot intersect: an invoice cannot be AMP and Keysend or Keysend and Bolt12, etc it could be useful to add an extra field to store this information instead of relying on checking how the invoice looks like.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
