//! Re-export of [`diesel`] with prelude types overridden with `async` variants
|
||||
//! from [`diesel_async`].
|
||||
//!
|
||||
//! # Usage
|
||||
//!
|
||||
//! To use `async` `diesel` support provided here, enable the following
|
||||
//! dependencies in your `Cargo.toml`:
|
||||
//!
|
||||
//! ```toml
|
||||
//! [dependencies]
|
||||
//! rocket = "=0.5.0-rc.3"
|
||||
//! diesel = "2"
|
||||
//!
|
||||
//! [dependencies.rocket_db_pools]
|
||||
//! version = "=0.1.0-rc.3"
|
||||
//! features = ["diesel_mysql"]
|
||||
//! ```
|
||||
//!
|
||||
//! Then, import `rocket_db_pools::diesel::prelude::*` as well as the
|
||||
//! appropriate pool type and, optionally, [`QueryResult`]. To use macros or
|
||||
//! `diesel` functions, use `diesel::` directly. That is, _do not_ import
|
||||
//! `rocket_db_pools::diesel`. Doing so will, by design, cause import errors.
|
||||
//!
|
||||
//! # Example
|
||||
//!
|
||||
//! ```rust
|
||||
//! # #[macro_use] extern crate rocket;
|
||||
//! # #[cfg(feature = "diesel_mysql")] {
|
||||
//! use rocket_db_pools::{Database, Connection};

//! use rocket_db_pools::diesel::{QueryResult, MysqlPool, prelude::*};
|

//! #[derive(Database)]
|
||||
//! #[database("diesel_mysql")]
|
||||
//! struct Db(MysqlPool);
|
||||
//!
|
||||
//! #[derive(Queryable, Insertable)]
|
||||
//! #[diesel(table_name = posts)]
|
||||
//! struct Post {
|
||||
//! id: i64,
|
||||
//! title: String,
|

//! published: bool,
