impl Clone for Uuid

fn clone(&self) -> Uuid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Uuid

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

Formats the value using the given formatter.

impl Default for Uuid

fn default() -> Uuid

Returns the “default value” for a type.

impl FromSql<Uuid, Pg> for Uuid

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

See the trait documentation.

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

impl HasSqlType<Uuid> for Pg

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

impl QueryId for Uuid

type QueryId = Uuid

fn query_id() -> Option<TypeId>

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

impl SqlType for Uuid

type IsNull = NotNull

Is this type nullable?

impl ToSql<Uuid, Pg> for Uuid

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, Pg>) -> Result

See the trait documentation.
