rbatis

v1.7.24

• fix support futures for tokio02

v1.7.23

• remove Tokio dep,only use async_std(Because it already supports Tokio02 and 03).
• you can use async_std choose tokio02 runtime

async-std = { version = "1.6", features = ["attributes","tokio02"] }

v1.7.21

• sqlite use MutexLock keep thread safe

v1.7.2

• add Log plugin
• add support disable/enable generated rust code print features for 'rbatis-macro-driver' toml.

v1.7.1

• fix connection Pool init with min_size(old version is init max_size)

v1.7.0

• use new of SyncMap(based on Tokio/AsyncStd's RWLock+std::HashMap)
  Older versions of dashmap block the runtime when a transaction starts，so we use new of SyncMap replace it!
  ‘SyncMap’ Ensure that when a transaction is running, simultaneous access to the transaction will only block the currently running coprocessor

this is impl rust code detail

#[cfg(feature = "runtime-async-std")]
pub(crate) use async_std::{
    sync::RwLock,
    sync::RwLockReadGuard,
    sync::RwLockWriteGuard
};

#[cfg(feature = "runtime-tokio")]
pub(crate) use tokio::{
    sync::RwLock,
    sync::RwLockReadGuard,
    sync::RwLockWriteGuard
};

use crate::runtime::{RwLock, RwLockReadGuard, RwLockWriteGuard};
pub struct SyncMap<K, V> where K: Eq + Hash {
    pub shard: RwLock<HashMap<K, V, RandomState>>,
}

• PagePlugin will be remove order by sql

v1.6.39

• 'sql' and 'py_sql' macro support page plugin

for example:

   //sql macro
    #[sql(RB, "select * from biz_activity where delete_flag = 0 and name = ?")]
    fn sql_select_page(page_req: &PageRequest, name: &str) -> Page<BizActivity> {}

    // py_sql macro
    #[py_sql(RB, "select * from biz_activity where delete_flag = 0
                  if name != '':
                    and name=#{name}")]
    fn py_select_page(page_req: &PageRequest, name: &str) -> Page<BizActivity> {}

v1.6.38

• recode proc macro for 'sql','py_sql' macro
• rename method RB.execute_parperd() to RB.exec_prepare()

v1.6.37

• support opt '-' in express engine

for example(node_test.rs):

d.a == null
express: d.a == null >>>>> true
'2019-02-26' == '2019-02-26'
express: '2019-02-26' == '2019-02-26' >>>>> true
`f`+`s`
express: `f`+`s` >>>>> "fs"
a +1 > b * 8
express: a +1 > b * 8 >>>>> false
a >= 0
express: a >= 0 >>>>> true
'a'+c
express: 'a'+c >>>>> "ac"
b
express: b >>>>> 2
a < 1
express: a < 1 >>>>> false
a +1 > b*8
express: a +1 > b*8 >>>>> false
a * b == 2
express: a * b == 2 >>>>> true
a - b == 0
express: a - b == 0 >>>>> false
a >= 0 && a != 0
express: a >= 0 && a != 0 >>>>> true
a == 1 && a != 0
express: a == 1 && a != 0 >>>>> true
1 > 3 
express: 1 > 3  >>>>> false
1 + 2 != nil
express: 1 + 2 != nil >>>>> true
1 != null
express: 1 != null >>>>> true
1 + 2 != nil && 1 > 0 
express: 1 + 2 != nil && 1 > 0  >>>>> true
1 + 2 != nil && 2 < b*8 
express: 1 + 2 != nil && 2 < b*8  >>>>> true
-1 != nil
express: -1 != nil >>>>> true
-1 != -2 && -1 == 2-3 
express: -1 != -2 && -1 == 2-3  >>>>> true
-1 == a*-1 
express: -1 == a*-1  >>>>> true
-1 + a*-1 
express: -1 + a*-1  >>>>> -2.0

v1.6.36

• fix py parser 's bug
• express support for example: '-1 != -1'

v1.6.35

• fix sql macro bug: not send 'tx_id'

v1.6.34

• macro auto gen CRUDEnable table_name return raw string.improve performance
• fix Manually implement CRUDEnable for table_columns() have whitespace bug。

v1.6.32

• add Raw identifiers support in CRUDEnable macro for #38

v1.6.31

• move sql '%' into arg for Wrapper. like(),not_like(),like_left(),like_right()

v1.6.3

• fix #30 fix stmt sql for Wrapper.like() method
• rewrite CRUDEnable trait, reduce needless method
• remove check arg len in 'sql' macro
• add ColumnFormat on CRUD update_by_wrapper,update_by_id
• fix some bugs

v1.6.2

• rbatis some method change arg type to Serialize trait(so you can send any Serialize value into this method)
• driver add bind sql type for bool
• add join test in crud_test.rs
• py_sql macro support add 'tx_id' into method

v1.6.0

• fix #31

v1.5.9

• Fix #30 #31 #29 and add custom format for sql type (for Postgres example : {}::timestamp )
• 修复了 Fix #30 #31 #29
• 增加了实验性的ColumnFormat 接口，已适应在某些特殊类型的转换（例如自定义转换 Postgres {}::timestamp）

v1.5.7

• 新增了宏生成py_sql的功能例如：

lazy_static! {
     static ref RB:Rbatis=Rbatis::new();
   }
#[py_sql(RB, "select * from biz_activity where id = #{name}
                  if name != '':
                    and name=#{name}")]
    fn py_select(name: &str) -> Option<BizActivity> {}

#[async_std::test]
    pub async fn test_macro_py_select() {
        fast_log::log::init_log("requests.log", &RuntimeType::Std);
        RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
        let a = py_select("1").await.unwrap();
        println!("{:?}", a);
    }
 INFO rbatis::rbatis - [rbatis] [] Query ==> select * from biz_activity where id =  ?  and name= ?
 INFO rbatis::rbatis - [rbatis] [] Args  ==> ["1","1"]

v1.5.6

• 修复了Pg数据库Varchar数据映射的一些bug
• 升级了BigDecimal库
• 表达式引擎支持none关键字识别
• 智能宏映射（新功能）同样较为方便

 lazy_static! {
     static ref RB:Rbatis=Rbatis::new();
   }
    /// 宏根据方法定义生成执行逻辑，又点类似于 java/mybatis的@select动态sql
    /// RB是本地依赖Rbatis引用的名称,例如  dao::RB, com::xxx::RB....都可以
    /// 第二个参数是标准的驱动sql，注意对应数据库参数mysql为？,pg为$1...
    /// 宏会自动转换函数为  pub async fn select(name: &str) -> rbatis_core::Result<BizActivity> {}
    ///
    #[sql(RB, "select * from biz_activity where id = ?")]
    fn select(name: &str) -> BizActivity {}
    //其他写法： pub async fn select(name: &str) -> rbatis_core::Result<BizActivity> {}

    #[async_std::test]
    pub async fn test_macro() {
        fast_log::log::init_log("requests.log", &RuntimeType::Std);
        RB.link("mysql://root:123456@localhost:3306/test").await.unwrap();
        let a = select("1").await.unwrap();
        println!("{:?}", a);
    }
