Trait Executor 

pub trait Executor {
    // Required method
    fn execute_query<'a>(
        &'a mut self,
        sql: &'a str,
    ) -> Pin<Box<dyn Future<Output = Result<QueryRows, DbError>> + Send + 'a>>;
}

最小执行器 trait

抽象了“执行 SQL 并返回结果行“的能力。 sz-orm-pool::Connection 和测试中的 Mock 连接都应实现此 trait。

Required Methods

fn execute_query<'a>( &'a mut self, sql: &'a str, ) -> Pin<Box<dyn Future<Output = Result<QueryRows, DbError>> + Send + 'a>>

执行查询 SQL，返回结果行

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
