How can I return the number of records modified by the update statement?

[aohanhe]

#[py_sql("update monitoring_host set online=false,last_offline_time=#{time} where host_code=#{host_code}")]
pub async fn update_offline_byhostcode(rb: &RBatis, host_code: String, time: DateTime) -> u32 {
impled!()
} 我试过这样是不行的，正确的做法是怎么样？
