Struct Oid 

pub struct Oid(pub u32);

The PostgreSQL OID type stores an object identifier, used internally by PostgreSQL as primary keys for various system tables.

Tuple Fields

0: u32

The raw unsigned integer value sent over the wire

Trait Implementations

impl Clone for Oid

fn clone(&self) -> Oid

Returns a duplicate 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 Decode<'_, Postgres> for Oid

fn decode(value: PgValueRef<'_>) -> Result<Self, BoxDynError>

Decode a new value of this type using a raw value from the database.

impl Default for Oid

fn default() -> Oid

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Oid

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode<'_, Postgres> for Oid

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, BoxDynError>

Writes the value of self into buf without moving self.

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

fn size_hint(&self) -> usize

impl Hash for Oid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Oid

fn eq(&self, other: &Oid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PgHasArrayType for Oid

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Serialize for Oid

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Type<Postgres> for Oid

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &<DB as Database>::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.

impl Copy for Oid

impl Eq for Oid

impl StructuralPartialEq for Oid
