The instruction.rs Module in the Rust Ethereum Virtual Machine (EVM)

The instruction.rs module defines interpretation mappings for EVM bytecode. It provides the definition of the Instruction struct, as well as the Opcode enumeration and the execute function, which runs a specific instruction.

Opcode Enum

The Opcode enum represents the opcodes that are available in the Ethereum Virtual Machine. Each variant corresponds to an operation that can be performed, such as addition, multiplication, subtraction, jumps, and memory operations.

Instruction Struct

The Instruction struct represents a single instruction in the EVM. It contains the opcode, which is the operation to be performed, and a list of bytes representing the operands for the instruction.

step Function

The step function interprets an instruction. It uses the opcode to determine what operation to perform and then performs the operation using the operands in the instruction.
