Mocking database

[HaronK]

Hi all,

For my project I need to mock a database for testing purposes.
My original idea was to create a MockDb structure and implement sqlx::Database trait for it but looks like it's not possible because Row and Column traits are sealed.
Is there a proper way to do database mocking.
Thanks.

I hit the same issue while trying to implement a new database type. What is the reason why these traits are sealed? Given that sqlx doesn't even use unsafe code (unless compiled with sqlite), I don't see the benefit of doing so. And it's a total roadblock when trying to implement the Database trait from outside of the crate.
