Trait Implementations

impl<'expr2, 'expr> AsExpression<Oid> for &'expr2 &'expr u32

type Expression = Bound<Oid, &'expr2 &'expr u32>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl<'expr> AsExpression<Oid> for &'expr u32

type Expression = Bound<Oid, &'expr u32>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl AsExpression<Oid> for u32

type Expression = Bound<Oid, u32>

The expression being returned

fn as_expression(self) -> Self::Expression

Perform the conversion

impl Clone for Oid

fn clone(&self) -> Oid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Oid

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

Formats the value using the given formatter.

impl Default for Oid

fn default() -> Oid

Returns the “default value” for a type.

impl FromSql<Oid, Pg> for u32

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

See the trait documentation.

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

A specialized variant of from_sql for handling null values.

impl HasSqlType<Oid> for Pg

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

Fetch the metadata for the given type

impl QueryId for Oid

type QueryId = Oid

A type which uniquely represents Self in a SQL query.

const 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 SqlType for Oid

type IsNull = NotNull

Is this type nullable?

impl ToSql<Oid, Pg> for u32

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

See the trait documentation.

impl Copy for Oid

impl SingleValue for Oid
