Struct EnvWithHandlerCfg

pub struct EnvWithHandlerCfg {
    pub env: Box<Env>,
    pub handler_cfg: HandlerCfg,
}

Evm environment with the chain spec id.

Fields

env: Box<Env>

Evm enironment.

handler_cfg: HandlerCfg

Handler configuration fields.

Implementations

impl EnvWithHandlerCfg

pub fn new(env: Box<Env>, handler_cfg: HandlerCfg) -> Self

Returns new EnvWithHandlerCfg instance.

pub fn new_with_spec_id(env: Box<Env>, spec_id: SpecId) -> Self

Returns new EnvWithHandlerCfg instance with the chain spec id.

is_optimism will be set to default value depending on optimism-default-handler feature.

pub fn new_with_cfg_env( cfg: CfgEnvWithHandlerCfg, block: BlockEnv, tx: TxEnv, ) -> Self

Takes CfgEnvWithHandlerCfg and returns new EnvWithHandlerCfg instance.

pub const fn spec_id(&self) -> SpecId

Returns the specification id.

pub fn enable_optimism(&mut self)

Enables the optimism handle register.

Methods from Deref<Target = Env>

pub fn clear(&mut self)

Resets environment to default values.

pub fn effective_gas_price(&self) -> U256

Calculates the effective gas price of the transaction.

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

Calculates the EIP-4844 data_fee of the transaction.

Returns None if Cancun is not enabled. This is enforced in Env::validate_block_env.

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

pub fn validate_block_env<SPEC: Spec>(&self) -> Result<(), InvalidHeader>

Validate the block environment.

pub fn validate_tx<SPEC: Spec>(&self) -> Result<(), InvalidTransaction>

Validate transaction data that is set inside ENV and return error if something is wrong.

Return initial spend gas (Gas needed to execute transaction).

pub fn validate_tx_against_state<SPEC: Spec>( &self, account: &mut Account, ) -> Result<(), InvalidTransaction>

Validate transaction against state.

Trait Implementations

impl Clone for EnvWithHandlerCfg

fn clone(&self) -> EnvWithHandlerCfg

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EnvWithHandlerCfg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EnvWithHandlerCfg

fn default() -> EnvWithHandlerCfg

Returns the “default value” for a type.

impl Deref for EnvWithHandlerCfg

type Target = Env

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for EnvWithHandlerCfg

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl PartialEq for EnvWithHandlerCfg

fn eq(&self, other: &EnvWithHandlerCfg) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
