unsigned char	label [33]
unsigned char	label_tweak [32]

Detailed Description

Labels.

The structs and callback function are implemented here as a demonstration of how the label lookup callback is meant to query a label cache and return the label tweak when a match is found. This is for demonstration purposes only and not optimized. In production, it is expected that the caller will be using a much more performant data structure for storing and querying labels, like e.g. a hash table with O(1) lookup cost.

Recipients not using labels can ignore these steps and simply pass NULL for the label_lookup and label_context arguments:

secp256k1_silentpayments_recipient_scan_outputs(..., NULL, NULL);
