• [u8; 8]

Examples

table! {
    devices {
        id -> Integer,
        macaddr -> MacAddr8,
    }
}

let inserted_macaddr = insert_into(devices)
    .values(macaddr.eq([0x08, 0x00, 0x2b, 0x01, 0x02, 0x03, 0x04, 0x05]))
    .returning(macaddr)
    .get_result::<[u8; 8]>(connection)?;
assert_eq!([0x08, 0x00, 0x2b, 0x01, 0x02, 0x03, 0x04, 0x05], inserted_macaddr);

impl Clone for MacAddr8

fn clone(&self) -> MacAddr8

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MacAddr8

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MacAddr8

fn default() -> MacAddr8

Returns the “default value” for a type.

impl FromSql<MacAddr8, Pg> for [u8; 8]

fn from_sql(value: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<DB::RawValue<'_>>) -> Result<Self>

fn metadata(_: &mut Self::MetadataLookup) -> PgTypeMetadata

Fetch the metadata for the given type

impl QueryId for MacAddr8

const HAS_STATIC_QUERY_ID: bool = true
