Because of the compile time, the annotations need to declare the database type to be used.

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.
