Trait for configuring the EVM for executing full blocks.

Required Associated Types

type DefaultExternalContext<'a>

Associated type for the default external context that should be configured for the EVM.

Required Methods

fn default_external_context<'a>(&self) -> Self::DefaultExternalContext<'a>

Provides the default external context.

Provided Methods

fn evm<DB: Database>( self, db: DB, ) -> Evm<'static, Self::DefaultExternalContext<'static>, DB>

where Self: Sized,

Returns new EVM with the given database

This does not automatically configure the EVM with crate::ConfigureEvmEnv methods. It is up to the caller to call an appropriate method to fill the transaction and block environment before executing any transactions using the provided EVM.

fn evm_with_env<'a, DB: Database + 'a>( &self, db: DB, env: EnvWithHandlerCfg, ) -> Evm<'a, Self::DefaultExternalContext<'a>, DB>

Returns a new EVM with the given database configured with the given environment settings, including the spec id.

This will preserve any handler modifications

fn evm_with_env_and_inspector<DB, I>( &self, db: DB, env: EnvWithHandlerCfg, inspector: I, ) -> Evm<'_, I, DB>

where DB: Database, I: GetInspector<DB>,

Returns a new EVM with the given database configured with the given environment settings, including the spec id.

This will use the given external inspector as the EVM external context.

This will preserve any handler modifications

fn evm_with_inspector<DB, I>(&self, db: DB, inspector: I) -> Evm<'_, I, DB>

where DB: Database, I: GetInspector<DB>,

Returns a new EVM with the given inspector.

Caution: This does not automatically configure the EVM with crate::ConfigureEvmEnv methods. It is up to the caller to call an appropriate method to fill the transaction and block environment before executing any transactions using the provided EVM.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
