Struct SessionContext 

pub struct SessionContext {
    pub session_id: String,
    pub metadata: HashMap<String, Value>,
    pub broadcaster: Option<Arc<dyn Any + Send + Sync>>,
    pub timestamp: u64,
    pub extensions: HashMap<String, Value>,
}

Minimal session context for JSON-RPC handlers.

Provides basic session information without imposing a transport. Designed to be passed by value (it is Clone) into handlers.

Field semantics

• session_id: opaque session identifier; format is caller’s choice.
• metadata: free-form key/value bag, persisted by the caller’s session storage if any.
• broadcaster: optional type-erased back-channel installed by the transport. Stored as Arc<dyn Any + Send + Sync> so this crate does not depend on any specific notification channel implementation. Downstream code (e.g. an MCP server) downcasts to its own concrete type.
• timestamp: Unix milliseconds when the context was created.
• extensions: request-scoped key/value bag for auth claims, middleware data, etc. Populated by the transport layer; never persisted.

Fields

session_id: String

Unique session identifier.

metadata: HashMap<String, Value>

Session metadata.

broadcaster: Option<Arc<dyn Any + Send + Sync>>

Optional type-erased broadcaster for session notifications.

Stored as Arc<dyn Any> to avoid coupling this crate to any specific notification channel type. Transport layers downcast as needed.

timestamp: u64

Session timestamp (Unix milliseconds).

extensions: HashMap<String, Value>

Request-scoped extensions (auth claims, middleware data).

Populated by the transport layer; never persisted to session storage by turul-rpc.

Trait Implementations

impl Clone for SessionContext

fn clone(&self) -> SessionContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionContext

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

Formats the value using the given formatter.
