Implementations§
Source§impl HtmlCache
impl HtmlCache
fn new(ttl: Duration, capacity: u64, max_page_bytes: usize) -> Self
fn generation(&self) -> u64
fn invalidate(&self) -> u64
Sourcefn swap_namespace(&self, namespace: &str) -> bool
fn swap_namespace(&self, namespace: &str) -> bool
切换命名空间:内容不同则整表失效并推进世代,保证旧命名空间下的已缓存 页面与在途回填都绝不返回给新命名空间(plan §6.7「release/flavor 纳入隔离」)。 同一进程内一个缓存实例只服务一个 release×flavor 组合,切换只发生在 启动/开发热重载重新组装路由时。返回是否真的发生了切换。
