Summary
### Impact Anyone who uses `total_size(..)` function to partial read the length of any `FixVec` will get an incorrect result, due to an incorrect implementation. This has been resolved in the 0.7.2 release. ### Workarounds If you already have the whole `FixVec` `A`, you can use `A.as_slice().len()` to get the total size of the `FixVec`. ### For more information If you have any questions or comments about this advisory: - [Open an issue to ask use directly](https://github.com/nervosnetwork/molecule/issues/new).
