Vectors in Rust use generics to create dynamically-sized arrays of any type.
|

The `into_dispose_nulls` function takes a vector as an argument, but only accepts vectors that store the &str type.
|

To allow the function to accept vectors that store any type, you can leverage your knowledge about generics.
