sizeHint method

@override int sizeHint(RuntimeMetadata 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(RuntimeMetadata metadata) {
  int size = SequenceCodec(PortableType.codec).sizeHint(metadata.types);
  size += SequenceCodec(PalletMetadata.codec).sizeHint(metadata.pallets);
  size += ExtrinsicMetadata.codec.sizeHint(metadata.extrinsic);
  size += TypeIdCodec.codec.sizeHint(metadata.runtimeTypeId);
  size += SequenceCodec(ApiMetadata.codec).sizeHint(metadata.apis);
  size += OuterEnumMetadata.codec.sizeHint(metadata.outerEnums);
  size += CustomMetadata.codec.sizeHint(metadata.custom);
  return size;
