Struct MacAddr

pub struct MacAddr;

Available on crate feature postgres_backend only.

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);

impl Clone for MacAddr

fn clone(&self) -> MacAddr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MacAddr

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

Formats the value using the given formatter.

impl Default for MacAddr

fn default() -> MacAddr

Returns the “default value” for a type.

impl FromSql<MacAddr, Pg> for [u8; 6]

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

See the trait documentation.

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

impl HasSqlType<MacAddr> for Pg

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

impl QueryId for MacAddr

const HAS_STATIC_QUERY_ID: bool = true

type QueryId = MacAddr

A type which uniquely represents Self in a SQL query.

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.
