reserveMemory method

@override Future<void> reserveMemory(int size, int priority)

ReserveMemory reserves memory/buffer space in the scope; the unit is bytes.

Implementation

@override
Future<void> reserveMemory(int size, int priority) async {
  if (_isDone) {
    throw _wrapError(network_errors.ResourceScopeClosedException());
  }
  var err = _resources.reserveMemory(size, priority);
  if (err != null) {
    // TODO: metrics.BlockMemory(size);
    throw _wrapError(err);
  }

  try {
    await _reserveMemoryForAncestors(size, priority);
  } catch (e) {
    _resources.releaseMemory(size); // Rollback local reservation
    // TODO: metrics.BlockMemory(size);
    throw _wrapError(e as Exception);
  }
  // TODO: trace.ReserveMemory(name, priority, size, _resources.memory);
  // TODO: metrics.AllowMemory(size);
}
