Implementations§

Source§

impl PrefetchManager

Source

pub fn new() -> Self

创建新的数据预取管理器

Source

pub fn register_prefetch<F, Fut>(&mut self, key: &str, prefetch_fn: F)
where F: Fn(&HashMap<String, String>, &HashMap<String, String>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<Value, String>> + Send + 'static,

注册数据预取函数

§Arguments
  • key - 预取函数的唯一标识
  • prefetch_fn - 预取函数
Source

pub async fn prefetch( &mut self, keys: &[&str], params: &HashMap<String, String>, query: &HashMap<String, String>, ) -> HashMap<String, Value>

执行数据预取

§Arguments
  • keys - 需要预取的键列表
  • params - 路由参数
  • query - 查询参数
§Returns
  • PrefetchContext - 预取的上下文数据
Source

pub fn clear_cache(&mut self)

清除预取缓存
