Hi
I am new to Rust and I am trying to use impl_select to get a row by username with Sqlite database. Please help with my code below.

#[derive(Clone, Debug, Serialize, Deserialize)]
pub struct AureumUsers {
pub user_id: u64,
pub username: String,
pub password: String,
pub first_name: String,
pub last_name: String,
pub address1: String,
pub address2: String,
pub city: String,
pub state: String,
pub postal_code: String,
pub mobile: String,
pub phone: String,
pub email: String,
pub birth_date: String,
pub kyc: bool,
pub create_date: String,
}
impl_select!(AureumUsers{select_by_username(table_name: String, username: &str) => "WHERE username = #{username}"});

pub async fn get_aureum_user (username: &str) {
let rb = open_db().await.unwrap();
let data = AureumUsers::select_by_username(&mut rb, "aureum_users".to_string(), username).await;
match data {
Ok(data) => println!("{:?}", data),
Err(err) => println!("Error: {}", err.to_string())
}
}

I am getting the following error when run the program.
Error: error while decoding value: invalid type: integer 0, expected a boolean
