Module transaction

Transaction types.

Modules

serde_bincode_compat

Bincode-compatible transaction type serde implementations.

signature

Handling transaction signature operations, including signature recovery, applying chain IDs, and EIP-2 validation.

util

Utility functions for signature.

Structs

BlobTransaction

A response to GetPooledTransactions that includes blob data, their commitments, and their corresponding proofs.

RecoveredTx

Signed transaction with recovered signer.

TransactionMeta

Additional fields in the context of a block that contains this transaction.

TransactionSigned

Signed transaction.

WithEncoded

Generic wrapper with encoded Bytes, such as transaction data.

Enums

InvalidTransactionError

Represents error variants that can happen when trying to validate a transaction.

PooledTransactionsElement

A response to GetPooledTransactions. This can include either a blob transaction, or a non-4844 signed transaction.

Transaction

A raw transaction.

TransactionConversionError

Represents error variants that can happen when trying to convert a transaction to pooled transaction.

TryFromRecoveredTransactionError

Represents error variants than can happen when trying to convert a recovered transaction.

TxType

Transaction Type

Constants

COMPACT_EXTENDED_IDENTIFIER_FLAG

For backwards compatibility purposes only 2 bits of the type are encoded in the identifier parameter. In the case of a COMPACT_EXTENDED_IDENTIFIER_FLAG, the full transaction type is read from the buffer as a single byte.

COMPACT_IDENTIFIER_EIP1559

Identifier parameter for EIP-1559 transaction

COMPACT_IDENTIFIER_EIP2930

Identifier parameter for EIP-2930 transaction

COMPACT_IDENTIFIER_LEGACY

Identifier parameter for legacy transaction

Statics

PARALLEL_SENDER_RECOVERY_THRESHOLD

Expected number of transactions where we can expect a speed-up by recovering the senders in parallel.

Traits

FillTxEnv

Implements behaviour to fill a TxEnv from another transaction.

SignedTransactionIntoRecoveredExt

Extension trait for SignedTransaction to convert it into RecoveredTx.

Functions

recover_signer

Recover signer address from message hash. This ensures that the signature S value is greater than secp256k1n / 2, as specified in EIP-2.

recover_signer_unchecked

Recover signer from message hash, without ensuring that the signature has a low s value.

recover_signers

Recovers a list of signers from a transaction list iterator.

recover_signers_unchecked

Recovers a list of signers from a transaction list iterator without ensuring that the signature has a low s value.

Type Aliases

PooledTransactionsElementEcRecovered

A signed pooled transaction with recovered signer.

TransactionSignedEcRecovered

Type alias kept for backward compatibility.
