Expand description

Required trait for all repositories to be compatible with es-entity and generate functions.

All repositories implement this trait to satisfy the basic requirements for type-safe database operations with the associated entity. The trait ensures validation that required fields (like entity) are present with compile-time errors. Implemented by the EsRepo derive macro with #[es_repo] attributes.

§Example


// Would show error for missing entity field if not provided in the `es_repo` attribute
#[derive(EsRepo, Debug)]
#[es_repo(entity = "User", columns(name(ty = "String")))]
pub struct Users {
    pool: PgPool,  // Required field for database operations
}

impl Users {
    pub fn new(pool: PgPool) -> Self {
        Self { pool }
   }
}
