diesel-crud

使用Rust特性和自动管理连接池的简单CRUD操作的规范API

该包处于早期阶段，并将根据所需的功能进行修改。

示例

以下可以成为您的包，用于在类型级别指定API。然后您只需要REST端点，这些端点接收JSON，并将其序列化到这些类型中，然后相应地更新数据库。

#[macro_use]
extern crate diesel;

pub mod schema;

use diesel::{Insertable, Queryable};
use diesel_crud::{Create, Load};
use schema::*;
use serde::{Deserialize, Serialize};

type Conn = diesel::pg::PgConnection;

#[derive(Debug, Clone, Serialize, Deserialize, Insertable)]
#[table_name = "users"]
pub struct CreateUser {
    pub username: String,
}

impl Create for CreateUser {
    type Table = users::table;

    fn table() -> Self::Table {
        users::table
    }
}

#[derive(Debug, Clone, Serialize, Deserialize, Queryable)]
pub struct User {
    pub id: i32,
    pub username: String,
}

struct GetUsers;

impl Load<Conn> for GetUsers {
    type Item = User;
    type Query = users::table;

    fn query(self) -> Self::Query {
        users::table
    }
}
