sizeHint method

@override int sizeHint(ApiMethodMetadata 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(ApiMethodMetadata metadata) {
  int size = StrCodec.codec.sizeHint(metadata.name);
  size += SequenceCodec(MethodInputEntryType.codec).sizeHint(metadata.inputs);
  size += TypeIdCodec.codec.sizeHint(metadata.output);
  size += SequenceCodec(StrCodec.codec).sizeHint(metadata.docs);
  return size;
}
