You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: many_count_relation.rs
    path of file: ./repos/prisma-engines/query-engine/connector-test-kit-rs/query-engine-tests/tests/queries/aggregation
    
    the code of the file until where you have to start completion: use query_engine_tests::*;

#[test_suite(schema(schema))]
mod many_count_rel {
    use indoc::indoc;
    use query_engine_tests::run_query;

    fn schema() -> String {
        let schema = indoc! {
            r#"model Post {
              #id(id, Int, @id)
              title      String
    
    
    async fn count_with_filters(runner: Runner) -> TestResult<()> {
        // 4 comment / 4 categories
        create_row(
            &runner,
            r#"{
                  id: 1,
                  title: "a",
                  comments: { create: [{id: 1}, {id: 2}, {id: 3}, {id: 4}] },
                  categories: { create: [{id: 1}, {id: 2}, {id: 3}, {id: 4}] }
            }"#,
        )
        .await?;

        insta::assert_snapshot!(
          run_query!(&runner, r#"{
            findManyPost(where: { id: 1 }) {
              comments(where: { id: 2 }) { id }
              categories(where: { id: 2 }) { id }
              _count { comments categories }
            }
          }"#),
          @r###"{"data":{"findManyPost":[{"comments":[{"id":2}],"categories":[{"id":2}],"_count":{"comments":4,"categories":4}}]}}"###
        );

        Ok(())
    }
