sizeHint method

  1. @override
int sizeHint(
  1. Option<E> value
)
override

If possible give a hint of expected size of the encoding.

This method is used inside default implementation of encode to avoid re-allocations.

Implementation

@override
int sizeHint(Option<E> value) {
  if (value.isNone) {
    return 1;
  }
  return 1 + subtypeCodec.sizeHint(value.value as E);
}
