Resolved EVM environment data needed by the EVM execution path.

Required Associated Types

type EvmTypes: EvmTypes

Runtime EVM type family.

Required Methods

fn spec_id(&self) -> <Self::EvmTypes as EvmTypesHost>::SpecId

Returns the active EVM specification.

fn chain_id(&self) -> u64

Returns the active chain ID.

fn block_env(&self) -> &BlockEnv<Self::EvmTypes>

Returns the configured block environment.

fn block_env_mut(&mut self) -> &mut BlockEnv<Self::EvmTypes>

Returns the configured block environment mutably.

fn version(&self) -> &Version

Returns the active EVM version.

fn version_mut(&mut self) -> &mut Version

Returns the active EVM version mutably.

fn block_base_fee(&self) -> u64

Returns the block base fee resolved for this environment.

fn block_blob_base_fee(&self) -> u64

Returns the block blob base fee resolved for this environment.

fn transaction_validation_limits(&self) -> EvmTransactionValidationLimits

Returns transaction validation limits active in this environment.

fn transaction_validation_gas_rules(&self) -> EvmTransactionValidationGasRules

Returns transaction validation gas rules active in this environment.

fn with_nonce_check_disabled(self) -> Self

Returns this environment with transaction nonce checks disabled.

fn with_balance_check_disabled(self) -> Self

Returns this environment with transaction balance checks disabled.

Provided Methods

fn uses_separate_block_gas(&self) -> bool

Returns whether the block uses independent regular and state gas capacity.

fn regular_gas_limit_cap(&self) -> u64

Returns the transaction limit used to reserve regular block gas.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
