sizeHint method
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(OuterEnumMetadata metadata) {
int size = TypeIdCodec.codec.sizeHint(metadata.callType);
size += TypeIdCodec.codec.sizeHint(metadata.eventType);
size += TypeIdCodec.codec.sizeHint(metadata.errorType);
return size;
}
