The following test case stop working:

https://github.com/FuelLabs/fuels-rs/tree/master/packages/fuels/tests/types/vectors

The regression was caused by 3fbad7b.

Printing errors with full call paths looks like:

120 |         assert(arg == expected);
    |                       ^^^^^^^^ This parameter was declared as type
std::vec::Vec<vectors::eq_impls::data_structures::SomeStruct<std::vec::Vec<std::vec::Vec<u32>>>>, but argument of type
std::vec::Vec<vectors::data_structures::SomeStruct<std::vec::Vec<std::vec::Vec<u32>>>> was provided.
