Контракт

• assert broadcast::channel(0) panics because broadcast capacity must be strictly positive
• assert tx.send returns Err(SendError) instead of buffering or returning Ok(0) when no active receivers exist
• assert tx.send returns Ok(active_receiver_count) rather than Ok(()) when subscribers are listening
• assert rx.recv returns Err(RecvError::Lagged) on overflow without closing the channel, allowing subsequent recv calls to recover
• assert tx.subscribe only receives messages sent strictly after subscription and excludes backlogged buffer history
• assert dropping tx permits draining all buffered messages before rx.recv yields Err(RecvError::Closed)
• assert rx.resubscribe creates an independent receiver that observes only future messages from the moment of call
