//! Transfer-related events for cross-module communication.
//!
//! This module defines lightweight event types used to wire SIP-layer
//! transfer notifications (e.g. REFER response/NOTIFY) up to the RWI
//! transfer controller without introducing circular dependencies.

pub type ReferNotifyTx = mpsc::UnboundedSender<ReferNotifyEvent>;

/// asynchronous REFER subscription NOTIFY.
