How to set a unique field in the mongodb rust implementation?
Are you supposed to use create_index()?
async fn create_id_fields(client: Client) -> Result {
let a = doc! {"my_id" => "1"}.unwrap;
client
.database(DB_NAME)
.collection(COLL_NAME_TICKET)
.create_index(a, unique = true)
.await;
}
Thanks for any hint!
async fn create_id_fields(client: &Client) {
let options = IndexOptions::builder().unique(true).build();
let model = IndexModel::builder()
.keys(doc! {"number": 1})
.options(options)
.build();
client
.database(DB_NAME)
.collection::<Raffle>(COLL_NAME_RAFFLE)
.create_index(model, None)
.await
.expect("error creating index!");
}
...so this is my solution but do i have to use the 'builder'?
To add to DZWG's answer, you may need to add a type to the 1.
async fn create_id_fields(client: &Client) {
let options = IndexOptions::builder().unique(true).build();
let model = IndexModel::builder()
.keys(doc! {"number": 1u32})
.options(options)
.build();
client
.database(DB_NAME)
.collection::<Raffle>(COLL_NAME_RAFFLE)
.create_index(model, None)
.await
.expect("error creating index!");
}
