#### 支持serde_json解码,支持BigDecimal，支持序列化，反序列化，支持async_std和tokio,支持自动判断数据库类型(支持mysql，pg，sqlite，tidb等等相关驱动)
```rust
fn main() -> Result<u64, rbatis_core::Error>{
async_std::task::block_on(
async move {
//Automatic judgment of database type
let pool = DBPool::new("mysql://root:123456@localhost:3306/test").await?;
let mut conn = pool.acquire().await?;
let count:u64 = conn.execute("SELECT count(1) FROM biz_activity;").await?;
println("count: {}",count);
return count;
}
);
}
```
