Trait Implementations

impl FromSql<Oid, Pg> for u32

fn from_sql(bytes: Option<&[u8]>) -> Result<Self>

See the trait documentation.

impl ToSql<Oid, Pg> for u32

fn to_sql<W: Write>(&self, out: &mut Output<W, Pg>) -> Result

See the trait documentation.

impl QueryId for Oid

type QueryId = Oid

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

fn query_id() -> Option<TypeId>

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

impl NotNull for Oid

impl SingleValue for Oid
