Struct bitcoin_blockfilter::BlockFilterIndex

pub struct BlockFilterIndex { /* private fields */ }

| BlockFilterIndex is used to store and | retrieve block filters, hashes, and | headers for a range of blocks by height. | An index is constructed for each supported | filter type with its own database (ie. | filter data for different types are | stored in separate databases). | | This index is used to serve BIP 157 net | requests. |
