Expand description

虚拟机主结构

基于栈的虚拟机实现，负责执行操作码序列

Implementations§

Source§

impl VM

Source

pub fn new() -> Self

创建新的虚拟机实例

初始化空的作用域栈和操作数栈

Source

pub fn run( &mut self, bytecode: &[Opcode], env: Variable, ) -> Result<Variable, VMError>

运行字节码

清空栈状态并执行给定的操作码序列

§参数
  • bytecode - 要执行的操作码数组
  • env - 执行环境变量
§返回值
  • VMResult<Variable> - 执行结果或错误
