Stores instructions for EVM.

Required Associated Types

type Context

Context type.

type InterpreterTypes: InterpreterTypes

Interpreter types.

Required Methods

fn instruction_table( &self, ) -> &InstructionTable<Self::InterpreterTypes, Self::Context>

Returns the instruction table that is used by EvmTr to execute instructions.

fn gas_params(&self) -> GasParams

Returns the gas params that is used by EvmTr to execute instructions.

fn set_spec(&mut self, spec: SpecId) -> bool

Sets the spec. Return true if the spec was changed.
