Struct InMemoryDistributedStorage 

pub struct InMemoryDistributedStorage { /* private fields */ }

In-memory distributed session storage implementation 内存分布式 Session 存储实现

For testing and development purposes 用于测试和开发目的

Implementations

impl InMemoryDistributedStorage

pub fn new() -> Self

Create a new in-memory storage 创建新的内存存储

Trait Implementations

impl Default for InMemoryDistributedStorage

fn default() -> Self

Returns the “default value” for a type.

impl DistributedSessionStorage for InMemoryDistributedStorage

fn save_session<'life0, 'async_trait>( &'life0 self, session: DistributedSession, _ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<(), SaTokenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Save session to memory storage | 保存会话到内存存储

Implementation Details | 实现细节

1. Stores session in main HashMap by session_id 在主 HashMap 中按 session_id 存储会话
2. Updates login_index for quick user lookup 更新 login_index 以快速查找用户

Note | 注意

TTL is ignored in memory storage (for simplicity). In production, use Redis or similar with built-in TTL support. 内存存储中忽略 TTL（为简化实现）。 在生产环境中，使用 Redis 或类似的内置 TTL 支持的存储。

fn get_session<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<DistributedSession>, SaTokenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get session from memory storage | 从内存存储获取会话

Returns | 返回

• Ok(Some(session)) - Session found | 找到会话
• Ok(None) - Session not found | 未找到会话

fn delete_session<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), SaTokenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete session from memory storage | 从内存存储删除会话

Implementation Details | 实现细节

1. Removes session from main HashMap 从主 HashMap 中移除会话
2. Removes session_id from login_index 从 login_index 中移除 session_id
3. Cleans up empty index entries 清理空的索引条目

fn get_sessions_by_login_id<'life0, 'life1, 'async_trait>( &'life0 self, login_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<DistributedSession>, SaTokenError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Get all sessions for a user | 获取用户的所有会话

Implementation Details | 实现细节

1. Looks up session_ids in login_index 在 login_index 中查找 session_ids
2. Retrieves full session data for each session_id 为每个 session_id 检索完整的会话数据
3. Filters out any missing sessions (cleanup) 过滤掉任何缺失的会话（清理）

Returns | 返回

Vector of all active sessions for the user 用户所有活跃会话的向量
