You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: person_alt.rs
    path of file: ./repos/TheReader/crates/backend/src/model
    
    the code of the file until where you have to start completion: use common::PersonId;
use sqlx::{FromRow, SqliteConnection};

use crate::Result;
use serde::Serialize;

#[derive(Debug, Serialize, FromRow)]
pub struct PersonAltModel {
    pub person_id: PersonId,
    pub name: Stri
    
    pub async fn delete_by_id(id: PersonId, db: &mut SqliteConnection) -> Result<u64> {
        let res = sqlx::query("DELETE FROM tag_person_alt WHERE person_id = $1")
            .bind(id)
            .execute(db)
            .await?;

        Ok(res.rows_affected())
    }
