Expand description
This represents the set of methods used to configure the EVM’s environment before block execution.
Default trait method implementation is done w.r.t. L1.
Required Associated Types§
Required Methods§
sourcefn fill_tx_env(
&self,
tx_env: &mut TxEnv,
transaction: &TransactionSigned,
sender: Address,
)
fn fill_tx_env( &self, tx_env: &mut TxEnv, transaction: &TransactionSigned, sender: Address, )
Fill transaction environment from a [TransactionSigned
] and the given sender address.
sourcefn fill_tx_env_system_contract_call(
&self,
env: &mut Env,
caller: Address,
contract: Address,
data: Bytes,
)
fn fill_tx_env_system_contract_call( &self, env: &mut Env, caller: Address, contract: Address, data: Bytes, )
Fill transaction environment with a system contract call.
sourcefn fill_cfg_env(
&self,
cfg_env: &mut CfgEnvWithHandlerCfg,
header: &Self::Header,
total_difficulty: U256,
)
fn fill_cfg_env( &self, cfg_env: &mut CfgEnvWithHandlerCfg, header: &Self::Header, total_difficulty: U256, )
Fill [CfgEnvWithHandlerCfg
] fields according to the chain spec and given header.
This must set the corresponding spec id in the handler cfg, based on timestamp or total difficulty
sourcefn fill_block_env(
&self,
block_env: &mut BlockEnv,
header: &Self::Header,
after_merge: bool,
)
fn fill_block_env( &self, block_env: &mut BlockEnv, header: &Self::Header, after_merge: bool, )
Fill [BlockEnv
] field according to the chain spec and given header
sourcefn next_cfg_and_block_env(
&self,
parent: &Self::Header,
attributes: NextBlockEnvAttributes,
) -> (CfgEnvWithHandlerCfg, BlockEnv)
fn next_cfg_and_block_env( &self, parent: &Self::Header, attributes: NextBlockEnvAttributes, ) -> (CfgEnvWithHandlerCfg, BlockEnv)
Returns the configured [CfgEnvWithHandlerCfg
] and [BlockEnv
] for parent + 1
block.
This is intended for usage in block building after the merge and requires additional attributes that can’t be derived from the parent block: attributes that are determined by the CL, such as the timestamp, suggested fee recipient, and randomness value.
Provided Methods§
sourcefn tx_env(&self, transaction: &TransactionSignedEcRecovered) -> TxEnv
fn tx_env(&self, transaction: &TransactionSignedEcRecovered) -> TxEnv
Returns a [TxEnv
] from a [TransactionSignedEcRecovered
].
sourcefn fill_cfg_and_block_env(
&self,
cfg: &mut CfgEnvWithHandlerCfg,
block_env: &mut BlockEnv,
header: &Self::Header,
total_difficulty: U256,
)
fn fill_cfg_and_block_env( &self, cfg: &mut CfgEnvWithHandlerCfg, block_env: &mut BlockEnv, header: &Self::Header, total_difficulty: U256, )
Convenience function to call both fill_cfg_env
and
ConfigureEvmEnv::fill_block_env
.
Note: Implementers should ensure that all fields are required fields are filled.
