Struct FunctionRegistry

Source 
pub struct FunctionRegistry { /* private fields */ }
Expand description

函数注册表

负责管理和查找所有可用的函数定义，包括内置函数和已废弃函数

Implementations§

Source§

impl FunctionRegistry

Source

pub fn get_definition(kind: &FunctionKind) -> Option<Rc<dyn FunctionDefinition>>

根据函数类型获取函数定义

§参数
  • kind - 函数类型（内置、已废弃、闭包或自定义）
§返回值
  • Some(Rc<dyn FunctionDefinition>) - 找到的函数定义
  • None - 未找到对应的函数定义
