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: variables.rs
    path of file: ./repos/async-graphql/tests
    
    the code of the file until where you have to start completion: use std::collections::HashMap;

use async_graphql::*;

#[tokio::test]
pub async fn test_variables() {
    struct Query;

    #[Object]
    impl Query {
        pub async fn int_val(&self, value: i32) -> i32 {
            value
        }

        pub async fn int_list_val(&self, value: Vec<i32>) -
    
pub async fn test_variable_no_value() {
    struct Query;

    #[Object]
    impl Query {
        pub async fn int_val(&self, value: Option<i32>) -> i32 {
            value.unwrap_or(10)
        }
    }

    let schema = Schema::new(Query, EmptyMutation, EmptySubscription);
    let resp = schema
        .execute(Request::new(
            r#"
            query QueryWithVariables($intVal: Int) {
                intVal(value: $intVal)
            }
        "#,
        ))
        .await
        .into_result()
        .unwrap();
    assert_eq!(
        resp.data,
        value!({
            "intVal": 10,
        })
    );
}
