Struct SessionInfo 

pub struct SessionInfo {
    pub session_id: String,
    pub client_capabilities: Option<ClientCapabilities>,
    pub server_capabilities: Option<ServerCapabilities>,
    pub state: HashMap<String, Value>,
    pub created_at: u64,
    pub last_activity: u64,
    pub is_initialized: bool,
    pub metadata: HashMap<String, Value>,
}

Core session storage traits and types for pluggable backend implementations Comprehensive session information

Fields

session_id: String

Unique session identifier (UUID v7 for temporal ordering)

client_capabilities: Option<ClientCapabilities>

Client capabilities negotiated during initialization

server_capabilities: Option<ServerCapabilities>

Server capabilities provided during initialization

state: HashMap<String, Value>

Session state key-value store

created_at: u64

Session creation timestamp (Unix millis)

last_activity: u64

Last activity timestamp (Unix millis)

is_initialized: bool

Whether session has completed MCP initialization

metadata: HashMap<String, Value>

Session metadata (connection info, user agent, etc.)

Implementations

impl SessionInfo

pub fn new() -> Self

Create a new session with UUID v7 for temporal ordering

pub fn with_id(session_id: String) -> Self

Create session with specific ID (for testing)

pub fn touch(&mut self)

Update last activity timestamp

pub fn is_expired(&self, timeout_minutes: u64) -> bool

Check if session is expired based on timeout

Trait Implementations

impl Clone for SessionInfo

fn clone(&self) -> SessionInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SessionInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SessionInfo

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SessionInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for SessionInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
