Classes
struct	txindex::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	txindex::BlockSeqKey
	Key for looking up the hash of the block with the given sequence number. More...
struct	txindex::BlockHashKey
	Key for looking up the sequence number assigned to the block with the given hash. More...
struct	txindex::DBKey

Namespaces
namespace	txindex

Typedefs

std::pair< uint8_t, uint256 >	txindex::LegacyTxKey (const Txid &txid)
	Key of a legacy (pre-hashing) txindex row: the full txid under the 't' prefix. More...

constexpr std::array< std::byte, 0 >	txindex::EMPTY_VALUE {}
	Empty value of a hashed txindex row, whose position is encoded in its key. More...
constexpr uint32_t	txindex::BLOCK_HEADER_SIZE {80}
