- 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 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]
extern crate rbatis;
use rbatis::crud::CRUD;
#[crud_enable]
#[derive(Clone, Debug)]

#[async_std::main]

macros (new addition)
lazy_static! {
static ref RB:Rbatis=Rbatis::new();
}
#[sql(RB, "select * from biz_activity where id = ?")]
pub async fn select(name: &str) -> BizActivity {}
#[async_std::test]
pub async fn test_macro() {
fast_log::init_log("requests.log", 1000, log::Level::Info, None, true);
RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
let a = select("1").await.unwrap();
println!("{:?}", a);
}
lazy_static! {
static ref RB:Rbatis=Rbatis::new();
}
#[py_sql(RB, "select * from biz_activity where id = #{name}
if name != '':
and name=#{name}")]
pub async fn py_select(name: &str) -> Option<BizActivity> {}
#[async_std::test]
pub async fn test_macro_py_select() {
fast_log::init_log("requests.log", 1000, log::Level::Info, None, true);
RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
let a = py_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 = init_rbatis().await;
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();
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());
{
"records": [
{
"id": "12312",
"name": "null",
"pc_link": "null",
"h5_link": "null",
"pc_banner_img": "null",
"h5_banner_img": "null",
"sort": "null",

"delete_flag": 1
}

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 = if name != null:
AND name like if ids != null:
AND id in (
trim ',':
for item in ids:
)"#;
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
async_std::task::block_on(async {
let rb = Rbatis::new();
rb.link("mysql://root:123456@localhost:3306/test").await.unwrap();
let context_id = "tx:1"; 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)
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<()> {
fast_log::init_log("requests.log", 1000, log::Level::Info, None, true);
RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
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'?
