Implementations

pub fn new() -> Self

创建新的模板渲染器

pub fn render( &self, template: &str, variables: &HashMap<String, Value>, ) -> Result<String>

渲染模板字符串

支持以下语法：

• {{var}} - 简单变量替换
• {{var.field}} - 嵌套访问
• {{var|default}} - 带默认值

pub fn extract_variables(&self, template: &str) -> Vec<String>

从模板中提取所有变量名

pub fn has_unresolved(&self, rendered: &str) -> bool

检查模板是否包含未解析的变量

pub fn render_params( &self, params: &HashMap<String, Value>, variables: &HashMap<String, Value>, ) -> Result<Value>

渲染参数 HashMap

对每个参数值，如果是字符串则渲染模板，否则保持原值
