Contributions summary:Raphael primarily contributed to the `sea-query` project by refactoring the codebase to utilize `IntoIterator` instead of `Vec` for various functions within the query builder. This involved modifications to the `select`, `update`, `delete`, and `insert` modules to enhance the library's flexibility. Further refactoring focused on correcting function signatures and removing unnecessary type specifications. This work improved the code's generality and potentially reduced unnecessary allocations.
