Struct BridgeCallContext 

pub struct BridgeCallContext {
    pub session_id: String,
    /* private fields */
}

Context for sync-blocking bridge calls from a V8 session.

Holds the frame sender and response receiver, session ID, call_id counter, and pending-call tracking. Used by V8 FunctionTemplate callbacks to implement the sync-blocking bridge pattern.

Fields

session_id: String

Session ID included in every BridgeCall

Implementations

impl BridgeCallContext

pub fn stub() -> Self

Create a no-op BridgeCallContext for snapshot stub functions. Panics if sync_call or async_send is called — stubs exist only for the bridge IIFE to reference (not call) during snapshot creation.

pub fn new( writer: Box<dyn Write + Send>, reader: Box<dyn Read + Send>, session_id: String, ) -> Self

Create a BridgeCallContext with a byte writer and reader (wraps in WriterFrameSender and ReaderResponseReceiver). Convenient for tests that pre-serialize BridgeResponse bytes.

pub fn with_receiver( sender: Box<dyn RuntimeEventSender>, response_rx: Box<dyn BridgeResponseReceiver>, session_id: String, router: CallIdRouter, shared_call_id: SharedCallIdCounter, ) -> Self

Create a BridgeCallContext with a FrameSender, ResponseReceiver, call_id routing table, and shared call_id counter. All sessions sharing the same CallIdRouter must share the same counter to prevent call_id collisions in the routing table.

pub fn sync_call_response( &self, method: &str, args: Vec<u8>, ) -> Result<Option<SyncBridgeCallResponse>, String>

Perform a sync-blocking bridge call.

Generates a unique call_id, sends a BridgeCall message over IPC, blocks on read() for the BridgeResponse, and returns the result. Error responses from the host are returned as Err.

pub fn sync_call( &self, method: &str, args: Vec<u8>, ) -> Result<Option<Vec<u8>>, String>

pub fn async_send(&self, method: &str, args: Vec<u8>) -> Result<u64, String>

Send a BridgeCall without blocking for a response. Returns the call_id for later matching with BridgeResponse. Used by async promise-returning bridge functions.

pub fn is_call_pending(&self, call_id: u64) -> bool

Check if a call_id is currently pending.

pub fn pending_count(&self) -> usize

Number of pending calls.
