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: create.rs
    path of file: ./repos/prisma-client-rust/integration-tests/tests
    
    the code of the file until where you have to start completion: use crate::db::*;
use crate::utils::*;

use prisma_client_rust::bigdecimal::BigDecimal;
use std::str::FromStr;

#[tokio::test]
async fn create() -> TestResult {
    let client = client().await;

    let post = client
        .post()
        .create(
            "Hi from Prisma!".to_string(),
            true,
            vec![post::desc::set(Some(
                "Prisma is a database toolkit that makes databases easy.".to_string(),
            ))],
        )
        .exec()
        .await?;
    
async fn unique_violation() -> TestResult {
    let client = client().await;

    let user = client
        .user()
        .create(
            "Brendan".to_string(),
            vec![user::id::set("user-1".to_string())],
        )
        .exec()
        .await?;

    assert_eq!(user.name, "Brendan");
    assert_eq!(user.id, "user-1");

    let user = client
        .user()
        .create(
            "Brendan".to_string(),
            vec![user::id::set("user-1".to_string())],
        )
        .exec()
        .await;

    assert!(user.is_err());

    cleanup(client).await
