pub struct Env<BlockT: Block, TxT: Transaction> {
    pub cfg: CfgEnv,
    pub block: BlockT,
    pub tx: TxT,
}
Expand description

EVM environment configuration.

Fields§

§cfg: CfgEnv

Configuration of the EVM itself.

§block: BlockT

Configuration of the block the transaction is in.

§tx: TxT

Configuration of the transaction that is being executed.

Implementations§

Source§

impl<BlockT: Block, TxT: Transaction> Env<BlockT, TxT>

Source

pub fn boxed(cfg: CfgEnv, block: BlockT, tx: TxT) -> Box<Self>

Create boxed Env.

Source

pub fn effective_gas_price(&self) -> U256

Source

pub fn calc_data_fee(&self) -> Option<U256>

Calculates the EIP-4844 data_fee of the transaction.

Returns None if Cancun is not enabled.

Source

pub fn calc_max_data_fee(&self) -> Option<U256>

Calculates the maximum [EIP-4844] data_fee of the transaction.

This is used for ensuring that the user has at least enough funds to pay the max_fee_per_blob_gas * total_blob_gas, on top of regular gas costs.

See EIP-4844: https://github.com/ethereum/EIPs/blob/master/EIPS/eip-4844.md#execution-layer-validation
