 TDengine has significantly improved the bind APIs to support data writing (INSERT) scenarios. Writing data in this way avoids the resource consumption of SQL syntax parsing, resulting in significant write performance improvements in many cases.

 Similar to the C interface, Rust provides the bind interface's wrapping. First, the [Taos][struct.taos] object creates a parameter binding object [Stmt] for an SQL statement.

 TDengine 的 Rust 连接器实现了参数绑定方式对数据写入（INSERT）场景的支持。采用这种方式写入数据时，能避免 SQL 语法解析的资源消耗，从而在很多情况下显著提升写入性能。

 与 C 接口类似，Rust 提供参数绑定接口。首先，通过 [Taos][struct.Taos] 对象创建一个 SQL 语句的参数绑定对象 [Stmt]：
