Struct TransactionSignedEcRecovered

pub struct TransactionSignedEcRecovered { /* private fields */ }

Signed transaction with recovered signer.

Implementations

impl TransactionSignedEcRecovered

pub const fn signer(&self) -> Address

Signer of transaction recovered from signature

pub const fn as_signed(&self) -> &TransactionSigned

Returns a reference to TransactionSigned

pub fn into_signed(self) -> TransactionSigned

Transform back to TransactionSigned

pub fn to_components(self) -> (TransactionSigned, Address)

Dissolve Self to its component

pub const fn from_signed_transaction( signed_transaction: TransactionSigned, signer: Address, ) -> Self

Create TransactionSignedEcRecovered from TransactionSigned and [Address] of the signer.

Methods from Deref<Target = TransactionSigned>

pub fn signature(&self) -> &Signature

Transaction signature.

pub fn transaction(&self) -> &Transaction

Transaction

pub fn hash(&self) -> TxHash

Transaction hash. Used to identify transaction.

pub fn hash_ref(&self) -> &TxHash

Reference to transaction hash. Used to identify transaction.

pub fn recover_signer(&self) -> Option<Address>

Recover signer from signature and hash.

Returns None if the transaction’s signature is invalid following EIP-2, see also recover_signer.

Note:

This can fail for some early ethereum mainnet transactions pre EIP-2, use Self::recover_signer_unchecked if you want to recover the signer without ensuring that the signature has a low s value.

pub fn recover_signer_unchecked(&self) -> Option<Address>

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

Returns None if the transaction’s signature is invalid, see also recover_signer_unchecked.

pub fn try_ecrecovered(&self) -> Option<TransactionSignedEcRecovered>

Tries to recover signer and return TransactionSignedEcRecovered by cloning the type.

pub fn recalculate_hash(&self) -> B256

Calculate transaction hash, eip2728 transaction does not contain rlp header and start with tx type.

pub fn size(&self) -> usize

Calculate a heuristic for the in-memory size of the TransactionSigned.

Methods from Deref<Target = Transaction>

pub fn signature_hash(&self) -> B256

Heavy operation that return signature hash over rlp encoded transaction. It is only for signature signing or signer recovery.

pub fn kind(&self) -> TxKind

Gets the transaction’s [TxKind], which is the address of the recipient or [TxKind::Create] if the transaction is a contract creation.

pub fn to(&self) -> Option<Address>

Get the transaction’s address of the contract that will be called, or the address that will receive the transfer.

Returns None if this is a CREATE transaction.

pub fn tx_type(&self) -> TxType

Get the transaction’s type

pub fn access_list(&self) -> Option<&AccessList>

Returns the [AccessList] of the transaction.

Returns None for legacy transactions.

pub fn authorization_list(&self) -> Option<&[SignedAuthorization]>

Returns the [SignedAuthorization] list of the transaction.

Returns None if this transaction is not EIP-7702.

pub fn is_dynamic_fee(&self) -> bool

Returns true if the tx supports dynamic fees

pub fn blob_versioned_hashes(&self) -> Option<Vec<B256>>

Blob versioned hashes for eip4844 transaction, for legacy, eip1559, eip2930 and eip7702 transactions this is None

This is also commonly referred to as the “blob versioned hashes” (BlobVersionedHashes).

pub fn blob_gas_used(&self) -> Option<u64>

Returns the blob gas used for all blobs of the EIP-4844 transaction if it is an EIP-4844 transaction.

This is the number of blobs times the DATA_GAS_PER_BLOB a single blob consumes.

pub fn effective_tip_per_gas(&self, base_fee: Option<u64>) -> Option<u128>

Returns the effective miner gas tip cap (gasTipCap) for the given base fee: min(maxFeePerGas - baseFee, maxPriorityFeePerGas)

If the base fee is None, the max_priority_fee_per_gas, or gas price for non-EIP1559 transactions is returned.

Returns None if the basefee is higher than the Transaction::max_fee_per_gas.

pub fn input(&self) -> &Bytes

Get the transaction’s input field.

pub fn encode_for_signing(&self, out: &mut dyn BufMut)

This encodes the transaction without the signature, and is only suitable for creating a hash intended for signing.

pub fn eip2718_encode(&self, signature: &Signature, out: &mut dyn BufMut)

Produces EIP-2718 encoding of the transaction

pub fn is_legacy(&self) -> bool

Returns true if the transaction is a legacy transaction.

pub fn is_eip2930(&self) -> bool

Returns true if the transaction is an EIP-2930 transaction.

pub fn is_eip1559(&self) -> bool

Returns true if the transaction is an EIP-1559 transaction.

pub fn is_eip4844(&self) -> bool

Returns true if the transaction is an EIP-4844 transaction.

pub fn is_eip7702(&self) -> bool

Returns true if the transaction is an EIP-7702 transaction.

pub fn as_legacy(&self) -> Option<&TxLegacy>

Returns the [TxLegacy] variant if the transaction is a legacy transaction.

pub fn as_eip2930(&self) -> Option<&TxEip2930>

Returns the [TxEip2930] variant if the transaction is an EIP-2930 transaction.

pub fn as_eip1559(&self) -> Option<&TxEip1559>

Returns the [TxEip1559] variant if the transaction is an EIP-1559 transaction.

pub fn as_eip4844(&self) -> Option<&TxEip4844>

Returns the [TxEip4844] variant if the transaction is an EIP-4844 transaction.

pub fn as_eip7702(&self) -> Option<&TxEip7702>

Returns the [TxEip7702] variant if the transaction is an EIP-7702 transaction.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
