It is an ORM, a small compiler, a dynamic SQL languages
- Non-invasive API design.You don't need to change the current code
- Compatible with most mybatis3 syntax
- No Runtimes，No Garbage Collection,High performance, Based on Future/Tokio
- Zero cost Dynamic SQL, implemented using (proc-macro,compile-time,Cow(Reduce unnecessary cloning)) techniques。 don't need ONGL engine(mybatis)
- JDBC-like driver design, driver use cargo.toml dependency and
Box<dyn Driver>separation - All database drivers supported
#{arg},${arg},?placeholder(pg/mssql auto processing '?' to '$1' and '@P1') - Dynamic SQL(Write code freely in SQL),pagination,
py_sqlquery lang andhtml_sql(Inspired Mybatis). - Dynamic configuration connection pool(Based on the deadpool)
- Supports logging, customizable logging based on
logcrate - 100% Safe Rust with
#![forbid(unsafe_code)]enabled - Support use Trait System Add
py_sql/ html_sqlfunctions.see - abs_admin project an complete background user management system( Vue.js+rbatis+actix-web)
Thanks to SQLX, deadpool, Tiberius, MyBatis,xorm and so on reference design or code implementation. release of V4.0
is Inspired and supported by these frameworks

}- Important update (pysql removes runtime, directly compiles to static rust code) This means that the performance of SQL generated using py_sql,html_sql is roughly similar to that of handwritten code.
Because of the compile time, the annotations need to declare the database type to be used.
#[py_sql("select * from biz_activity where delete_flag = 0
if name != '':
`and name=#{name}`")]
async fn py_sql_tx(rb: &Rbatis, tx_id: &String, name: &str) -> Vec<BizActivity> { impled!() }- Added html_sql support, a form of organization similar to MyBatis, to facilitate migration of Java systems to Rust( Note that it is also compiled as Rust code at build time and performs close to handwritten code) this is very faster

}Rely on rbatis-codegen to create the source code of the corresponding structure from the html file at compile time (with debug_mode(Cargo.toml- rbatis = { features = ["debug_mode"]}) enabled, you can observe the code-generated function), and call the generated method directly at run time.
We know that compilation is generally divided into three steps, lexes, syntactic analysis, semantic analysis, and intermediate code generation. In rbatis,
Lexical analysis is handled by the dependent func.rs in rbatis-codegen, which relies on syn and quote.
Parsing is done by parser_html and parser_pysql in rbatis-codegen
The generated syntax tree is a structure defined in the syntax_tree package in rbatis-codegen
Intermediate code generation has func.rs generation function, all supported functions are defined in rbatis-codegen
What is described above occurs during the cargo build phase, which is the compilation phase of the rust procedural macro, where the code generated by rbatis-codegen is handed back to the rust compiler for LLVM compilation to produce pure machine code
So I think rbatis is Truly zero overhead dynamic SQL compile-time ORM.
You are welcome to submit the merge, and make sure that any functionality you add has the appropriate mock unit test function added under the test package.
- sqlite table sync plugin(auto create table/column)
- connection pool add more dynamically configured parameters
- More simplified syntax
