* Fixes integrity tests

* Minor fixes

* Updates trait bounds

* Uses custom bound for AsPrimitive

* Fixes trait bounds

* Revert "Fixes trait bounds"

This reverts commit 0b0f42f583f3a616a88afe45fcd06d31e7d9a06f.

* Revert "Uses custom bound for AsPrimitive"

This reverts commit 838e5281adf8b6e9632a2abb9cd550db4ae24126.
