Examples

use ruststream_sqlx::dialect::Column;
use ruststream_sqlx::outbox::spec::own;
use ruststream_sqlx::outbox::{self, OutboxSpec, OutboxTable};
use sqlx::{PgConnection, PgPool, Postgres};

#[derive(sqlx::FromRow)]
pub struct OrderEvent {
    id: i64,
    name: String,
    payload: Vec<u8>,
}

impl OutboxTable for OrderEvent {
    type Id = i64;
    type Table = OutboxSpec<(own::Recover,)>;
    const TABLE: Self::Table = OutboxSpec::new(
        "outbox",
        Column::new("id"),
        Column::new("name"),
        Column::new("payload"),
    )
    .own::<own::Recover>();
}

// The startup republish sends the records oldest first.
impl outbox::Recover<Postgres> for OrderEvent {
    async fn recover(conn: &mut PgConnection, name: &str) -> sqlx::Result<Vec<Self>> {
        sqlx::query_as("SELECT id, name, payload FROM outbox WHERE name = $1 ORDER BY id")
            .bind(name)
            .fetch_all(conn)
            .await
    }
}
