Expand description

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

The callback receives GetEvent 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.
