Type Alias SyncCallback

pub type SyncCallback = Arc<dyn Fn(SyncEvent) -> Pin<Box<dyn Future<Output = Result<bool, Box<dyn Error + Send + Sync>>> + Send + Sync>> + Send + Sync>;

Callback type used during sync operations to report progress and allow cancellation.

The callback receives SyncEvent variants and returns a Future that resolves to:

• Ok(true): Continue the operation.
• Ok(false): Cancel the operation (results in Error::OperationCancelled).
• Err(e): Propagate an error from the callback.
