BIP 158 Compact Block Filters for Light Clients.

This module implements a structure for compact filters on block data, for use in the BIP 157 light client protocol. The filter construction proposed is an alternative to Bloom filters, as used in BIP 37, that minimizes filter size by using Golomb-Rice coding for compression.

§Relevant BIPS

§Examples

fn get_script_for_coin(coin: &OutPoint) -> Result<ScriptBuf, BlockFilterError> {
  // get utxo ...
}

// create a block filter for a block (server side)
let filter = BlockFilter::new_script_filter(&block, get_script_for_coin)?;

// or create a filter from known raw data
let filter = BlockFilter::new(content);

// read and evaluate a filter

let query: Iterator<Item=ScriptBuf> = // .. some scripts you care about
if filter.match_any(&block_hash, &mut query.map(|s| s.as_bytes())) {
  // get this block
}
