}Expand description
Main Transaction trait that abstracts and specifies all transaction currently supported by Ethereum.
Access to any associated type is gaited behind tx_type function.
It can be extended to support new transaction types and only transaction types can be deprecated by not returning tx_type.
Required Associated Types§
Sourcetype TransactionError: TransactionError
type TransactionError: TransactionError
An error that occurs when validating a transaction.
Sourcetype TransactionType: Into<TransactionType>
type TransactionType: Into<TransactionType>
Transaction type.
Sourcetype AccessList: AccessListTrait
type AccessList: AccessListTrait
Access list type.
type Legacy: LegacyTx
type Eip2930: Eip2930Tx<AccessList = Self::AccessList>
type Eip1559: Eip1559Tx<AccessList = Self::AccessList>
type Eip4844: Eip4844Tx<AccessList = Self::AccessList>
type Eip7702: Eip7702Tx<AccessList = Self::AccessList>
Required Methods§
Sourcefn tx_type(&self) -> Self::TransactionType
fn tx_type(&self) -> Self::TransactionType
Transaction type. Depending on this field other functions should be called.
If transaction is Legacy, then legacy() should be called.
Provided Methods§
Sourcefn common_fields(&self) -> &dyn CommonTxFields
fn common_fields(&self) -> &dyn CommonTxFields
Common fields for all transactions.
Sourcefn effective_gas_price(&self, base_fee: U256) -> U256
fn effective_gas_price(&self, base_fee: U256) -> U256
Effective gas price is gas price field for Legacy and Eip2930 transaction While for transactions after Eip1559 it is minimum of max_fee and base+max_priority_fee.
Sourcefn access_list(&self) -> Option<&Self::AccessList>
fn access_list(&self) -> Option<&Self::AccessList>
Returns access list.
