NewBloomIndexer returns a chain indexer that generates bloom bits data for the canonical chain for fast logs filtering.

NewChainIndexer creates a new chain indexer to do background processing on chain segments of a given size after certain number of confirmations passed.

BloomIndexer implements a core.ChainIndexer, building up a rotated bloom bits index for the Ethereum header bloom filters, permitting blazing fast filtering.

ChainIndexer does a post-processing job for equally sized sections of the canonical chain (like BlooomBits and CHT structures).
