Struct TemplateEngine 

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

Tera 模板引擎封装

扫描指定目录下的 .tera 文件并注册到内部 Tera 实例, 提供模板渲染、类型校验等能力。

Implementations§

Source§

impl TemplateEngine

Source

pub async fn init(template_dir: &Path) -> Result<Self, CliError>

初始化模板引擎

扫描 template_dir 下全部 .tera 文件并注册到 Tera 实例。 每个子目录代表一种模板类型(如 plugin-crud、plugin-master-slave)。

§错误
  • CliError::TemplateMissing:目录不存在
  • CliError::TemplateSyntaxError:模板语法错误(含文件名/行号/列号)
Source

pub fn render( &self, template_name: &str, context: &Context, ) -> Result<String, CliError>

渲染模板

§错误
  • CliError::VarNotFound:模板变量缺失(含变量名/引用文件/行号)
  • CliError::Generic:其他渲染错误
Source

pub fn list_templates(&self) -> Vec<String>

返回可用模板类型列表(模板根目录下的子目录名)

Source

pub fn validate_template_type( &self, template_type: &str, ) -> Result<(), CliError>

校验模板类型是否存在

§错误
  • CliError::UnknownTemplate:模板类型不存在,附带可用模板列表
Source

pub fn template_dir(&self) -> &Path

返回模板根目录
