构造缓存键 | Build a cache key

pub async fn get_or_load<F, Fut>( &self, key: String, loader: F, ) -> SaTokenResult<Arc<[String]>>

where F: FnOnce() -> Fut, Fut: Future<Output = SaTokenResult<Vec<String>>>,

读取或加载 | Get or load

pub fn invalidate(&self, key: &str)

失效单个键 | Invalidate one key

pub fn invalidate_account(&self, login_type: &str, login_id: &str)

失效某账号在某体系下的权限与角色两条缓存。 Invalidate both the permission and role entries of an account.
