sizeHint method

@override int sizeHint(RuntimeMetadataV14 metadata)

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(RuntimeMetadataV14 metadata) {
  int size = SequenceCodec(PortableType.codec).sizeHint(metadata.types);
  size += SequenceCodec(PalletMetadataV14.codec).sizeHint(metadata.pallets);
  size += ExtrinsicMetadataV14.codec.sizeHint(metadata.extrinsic);
  size += TypeIdCodec.codec.sizeHint(metadata.runtimeTypeId);
  return size;
}
