sz-rust-core 0.2.1

//! 编译时 SQL 检查宏集成测试
//!
//! 验证 `sz_rust_core::sql_string!` 宏的重导出可用性。
//!
//! 注意：`sql_string!` 是编译时宏，校验失败会触发 `compile_error!`，
//! 因此本测试文件本身通过编译即证明合法 SQL 被正确接受。
//! 对于非法 SQL 的拒绝路径，由 `sz-orm-macros` 自身的单元测试覆盖
//! （见 `sz-orm/packages/sz-orm-macros/src/lib.rs` 中的 `validate_sql_content` 测试）。
