txindex Namespace Reference

Classes
struct	BlockHashKey
	Key for looking up the sequence number assigned to the block with the given hash. More...
struct	BlockSeqKey
	Key for looking up the hash of the block with the given sequence number. More...
struct	BlockTxPosition
	The location of a transaction: the sequence number of the block that contains it and the transaction's serialized byte offset from the start of that block (including the header), so the on-disk position is simply block_data_pos + tx_offset_in_block. More...
struct	DBKey
