A highly Performant,Safe,Dynamic SQL ORM framework written in Rust, inspired by Mybatis and MybatisPlus.

Why not diesel or not sqlx ?

Framework	Async/.await	Learning curve	Dynamic SQL/py/Wrapper/built-in CRUD	Logical delete plugin	Pagination plugin
rbatis	√	easy	√	√	√
sqlx	√	hard (depends on macros and env. variables)	x	x	x
diesel	x	hard (use FFI, unsafe)	x	x	x

Performance comparison with Golang (in a docker environment)

Framework	Mysql（docker）	SQL statement（10k）	ns/operation（lower is better）	Qps(higher is better)	Memory usage(lower is better）
Rust-rbatis/tokio	1 CPU, 1G memory	select count(1) from table;	965649 ns/op	1035 Qps/s	2.1MB
Go-GoMybatis/http	1 CPU, 1G memory	select count(1) from table;	1184503 ns/op	844 Qps/s	28.4MB

used json with serde_json for passing parameters and communication
high performance, single threaded benchmark can easily achieve 200,000 QPS - data returned from database directly ( zero lookup time) on a Windows 10 6 core i7 with 16 GB memory machine. Performace will be better using multiple threads, and it outperforms Go's GoMyBatis.
supports logical deletes, pagination, py-like SQL and basic Mybatis functionalities.
supports future,(in theory, if all io operations are replaced with async_std/tokio, it could achieve higher concurrency than Go-lang)
supports logging, customizable logging based on log crate
used 100% safe Rust with #![forbid(unsafe_code)] enabled
rbatis/example (import into Clion!)
abs_admin project

Example Rust backend service https://github.com/rbatis/abs_admin

Example Cargo.toml

# add this library,and cargo install

# json (required)
serde = { version = "1", features = ["derive"] }
serde_json = "1"

# Date time (required)
chrono = { version = "0.4", features = ["serde"] }

# logging lib(required)
log = "0.4"
fast_log="1.3"

# BigDecimal lib(optional)
bigdecimal = "0.2"

# rbatis lib(required)
rbatis =  { version = "1.8" }

Quick example: QueryWrapper and common usages (see example/crud_test.rs for details)

//#[macro_use] define in 'root crate' or 'mod.rs' or 'main.rs'
#[macro_use]

/// may also write `CRUDTable` as `impl CRUDTable for BizActivity{}`

/// #[crud_enable(id_name:"id"|id_type:"String"|table_name:"biz_activity"|table_columns:"id,name,version,delete_flag"|formats_pg:"id:{}::uuid")]
#[crud_enable]
#[derive(Clone, Debug)]

  pub status: Option<i32>,
  pub remark: Option<String>,
  pub create_time: Option<NaiveDateTime>,

macros (new addition)

#[macro_use]
extern crate lazy_static;

lazy_static! {
  static ref RB:Rbatis=Rbatis::new();
}

/// Other code writing way:
/// #[py_sql(RB, "select * from biz_activity where id = #{name}

#[macro_use]

    let a = select("1").await.unwrap();
    println!("{:?}", a);
}

How to use logical deletes plugin (works for fetching or removing functions provided by rbatis，e.g. list(),remove()，fetch**())

let mut rb:Rbatis=Rbatis::new();
//rb.logic_plugin = Some(Box::new(RbatisLogicDeletePlugin::new_opt("delete_flag",1,0)));//Customize deleted/undeleted writing
rb.logic_plugin = Some(Box::new(RbatisLogicDeletePlugin::new("delete_flag")));
rb.link("mysql://root:123456@localhost:3306/test").await.unwrap();
let r = rb.remove_batch_by_id::<BizActivity>("", & ["1".to_string(), "2".to_string()]).await;
if r.is_err() {
  println ! ("{}", r.err().unwrap().to_string());
}

How to use pagination plugin

let mut rb = Rbatis::new();
rb.link("mysql://root:123456@localhost:3306/test").await.unwrap();
//replace page plugin
//rb.page_plugin = Box::new(RbatisPagePlugin::new());

let req = PageRequest::new(1, 20);
let wraper= rb.new_wrapper()
.eq("delete_flag", 1);
let data: Page<BizActivity> = rb.fetch_page_by_wrapper("", & wraper, & req).await.unwrap();
println!("{}", serde_json::to_string(&data).unwrap());

//2020-07-10T21:28:40.036506700+08:00 INFO rbatis::rbatis - [rbatis] Query ==> SELECT count(1) FROM biz_activity  WHERE delete_flag =  ? LIMIT 0,20

py-like sql example

//Execute to remote mysql and get the result. Supports any serializable type of SERde_JSON
        let rb = Rbatis::new();
        rb.link("mysql://root:123456@localhost:3306/test").await.unwrap();
            let py = r#"
        SELECT * FROM biz_activity
        WHERE delete_flag = #{delete_flag}
        if name != null:
          AND name like #{name+'%'}
        if ids != null:
          AND id in (
          trim ',':
             for item in ids:
               #{item},
          )"#;
            let data: serde_json::Value = rb.py_fetch("", py, &json!({   "delete_flag": 1 })).await.unwrap();
            println!("{}", data);

logging system with fast_log here as an example

 use log::{error, info, warn};
 fn  main(){
      fast_log::init_log("requests.log", 1000, log::Level::Info, None, true);
      info!("print data");
 }

Customize connection pool's size, timeout, active number of connections, and etc.

use rbatis::core::db::PoolOptions;

pub async fn init_rbatis() -> Rbatis {
    let rb = Rbatis::new();
    let mut opt = PoolOptions::new();
    opt.max_size = 20;
    rb.link_opt("mysql://root:123456@localhost:3306/test", &opt).await.unwrap();
}

`Async/.await` task support

        let rb = Rbatis::new();
        rb.link("mysql://root:123456@localhost:3306/test").await.unwrap();
        let context_id = "tx:1";//事务id号
        rb.begin(context_id).await.unwrap();
        let v: serde_json::Value = rb.fetch(context_id, "SELECT count(1) FROM biz_activity;").await.unwrap();
        println!("{}", v.clone());
        rb.commit(context_id).await.unwrap();

How to use rbatis with Rust web frameworks (actix-web is used here as an example, but all web frameworks based on tokio or async_std are supported)

#[macro_use]
extern crate lazy_static;
lazy_static! {
   static ref RB:Rbatis=Rbatis::new();
}

async fn index() -> impl Responder {
    let v:Result<i32,rbatis::core::Error> = RB.fetch("", "SELECT count(1) FROM biz_activity;").await;
    HttpResponse::Ok().body(format!("count(1)={}",v.unwrap_or(0)))
}

#[actix_rt::main]
async fn main() -> std::io::Result<()> {
    //log
    fast_log::init_log("requests.log", 1000, log::Level::Info, None, true);
    //link database
    RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
    //http server
    HttpServer::new(|| {
        App::new()
            .route("/", web::get().to(index))
    })
        .bind("127.0.0.1:8000")?
        .run()
        .await
}

Conlusion: Assuming zero time consumed on IO, single threaded benchmark achieves 200K QPS or QPS, which is a few times more performant than GC languages like Go or Java.

FAQ

Postgres Types Define Please see Doc

中文

English Doc

Support for DateTime and BigDecimal?
Currently supports chrono::NaiveDateTime和bigdecimal::BigDecimal
Supports for async/.await
Currently supports both async_std and tokio
Stmt in postgres uses $1, $2 instead of ? in Mysql, does this require some special treatment? No, because rbatis uses #{} to describe parametric variabls, you only need to write the correct parameter names and do not need to match it with the symbols used by the database.
Supports for Oracle database driver?
No, moving away from IOE is recommended.
Which crate should be depended on if only the driver is needed?
rbatis-core， Cargo.toml add rbatis-core = "*"
How to select async/.await runtime?
see https://rbatis.github.io/rbatis.io/#/en/
column "id" is of type uuid but expression is of type text'?
