sizeHint method

@override int sizeHint(VariantDef value)

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(VariantDef value) {
  var size = 0;
  size += StrCodec.codec.sizeHint(value.name);
  size += SequenceCodec(Field.codec).sizeHint(value.fields);
  size += U8Codec.codec.sizeHint(value.index);
  size += SequenceCodec(StrCodec.codec).sizeHint(value.docs);
  return size;
}
