pub struct MacAddr;
Available on crate feature postgres_backend only.
Expand description

The MACADDR SQL type.

§ToSql impls

  • [u8; 6]

§FromSql impls

  • [u8; 6]

§Examples

table! {
    devices {
        id -> Integer,
        macaddr -> MacAddr,
    }
}

let inserted_macaddr = insert_into(devices)
    .values(macaddr.eq([0x08, 0x00, 0x2b, 0x01, 0x02, 0x03]))
    .returning(macaddr)
    .get_result::<[u8; 6]>(connection)?;
assert_eq!([0x08, 0x00, 0x2b, 0x01, 0x02, 0x03], inserted_macaddr);
