eth::codec

Classes

	Name
struct	eth::codec::LogEntry EVM log entry emitted by a CALL or CREATE instruction.
struct	eth::codec::AccessListEntry An EIP-2930 access list entry: contract address + storage slots.
struct	eth::codec::Transaction Full Ethereum transaction covering legacy, EIP-2930 and EIP-1559 formats.
struct	eth::codec::Receipt
struct	eth::codec::BlockHeader

Types

	Name
enum class uint8_t	TransactionType { kLegacy = 0x00, kAccessList = 0x01, kDynamicFee = 0x02} Ethereum transaction types per EIP-2718.
using rlp::Hash256	Hash256
using rlp::Address	Address
using rlp::Bloom	Bloom
using std::vector< uint8_t >	ByteBuffer
using rlp::EncodingResult< ByteBuffer >	EncodeResult
template <typename T > using rlp::Result< T >	DecodeResult

Functions

	Name
EncodeResult	encode_log_entry(const LogEntry & entry)
DecodeResult< LogEntry >	decode_log_entry(rlp::ByteView rlp_data)
EncodeResult	encode_access_list_entry(const AccessListEntry & entry)
DecodeResult< AccessListEntry >	decode_access_list_entry(rlp::ByteView rlp_data)
EncodeResult	encode_transaction(const Transaction & tx) Encode a transaction. Typed transactions (EIP-2930, EIP-1559) are prefixed with their type byte before the RLP payload, per EIP-2718.
DecodeResult< Transaction >	decode_transaction(rlp::ByteView raw_data)
EncodeResult	encode_receipt(const Receipt & receipt)
DecodeResult< Receipt >	decode_receipt(rlp::ByteView rlp_data)
