Struct Isolate

pub struct Isolate<'arena> { /* private fields */ }

Isolate 是一个组件，用于封装一个隔离的环境，用于执行表达式。

重新运行 Isolate 允许通过 arena 分配器进行高效的内存重用。 arena 分配器通过重用内存块来优化内存管理，从而在 Isolate 被多次重用时提高性能和资源利用率。

🆕 现在支持扩展机制和State集成

Implementations

impl<'a> Isolate<'a>

pub fn new() -> Self

pub fn with_environment(variable: Variable) -> Self

pub fn set_environment(&mut self, variable: Variable)

pub fn update_environment<F>(&mut self, updater: F)

where F: FnMut(Option<&mut Variable>),

pub fn set_reference(&mut self, reference: &'a str) -> Result<(), IsolateError>

pub fn get_reference(&self, reference: &str) -> Option<Variable>

pub fn clear_references(&mut self)

pub fn compile_standard( &mut self, source: &'a str, ) -> Result<Expression<Standard>, IsolateError>

pub fn run_standard( &mut self, source: &'a str, ) -> Result<Variable, IsolateError>

pub fn run_standard_with_state( &mut self, source: &'a str, state: Arc<State>, ) -> Result<Variable, IsolateError>

运行标准表达式，并传入State供自定义函数使用

使用 RAII 模式确保 State 的异常安全管理

pub fn compile_unary( &mut self, source: &'a str, ) -> Result<Expression<Unary>, IsolateError>

pub fn run_unary(&mut self, source: &'a str) -> Result<bool, IsolateError>

pub fn run_unary_with_state( &mut self, source: &'a str, state: Arc<State>, ) -> Result<bool, IsolateError>

运行一元表达式，并传入State供自定义函数使用

使用 RAII 模式确保 State 的异常安全管理

pub fn register_custom_function<F>( name: String, params: Vec<VariableType>, return_type: VariableType, executor: F, ) -> Result<(), String>

where F: Fn(&Arguments<'_>, Option<&Arc<State>>) -> Result<Variable, Error> + 'static,

注册自定义函数（可在表达式中直接调用）

pub fn list_custom_functions() -> Vec<String>

列出所有已注册的自定义函数

pub fn clear_custom_functions()

清空所有自定义函数
