Examples

use diesel_geometry::data_types::PgPoint;


table! {
    use diesel::sql_types::*;
    use diesel_geometry::sql_types::Point;
    items {
        id -> Integer,
        name -> VarChar,
        location -> Point,
    }
}

let inserted_location = insert_into(items)
    .values((name.eq("Shiny Thing"), location.eq(PgPoint(3.1, 9.4))))
    .returning(location)
    .get_result(&connection);
assert_eq!(Ok(PgPoint(3.1, 9.4)), inserted_location);
