Trait Implementations

impl Clone for Cell

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cell

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

Formats the value using the given formatter.

impl Display for Cell

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

Formats the value using the given formatter.

impl FromDatum for Cell

unsafe fn from_polymorphic_datum( datum: Datum, is_null: bool, typoid: Oid, ) -> Option<Self>

where Self: Sized,

Like from_datum for instantiating polymorphic types which require preserving the dynamic type metadata.

const GET_TYPOID: bool = false

Should a type OID be fetched when calling from_datum?

unsafe fn from_datum(datum: Datum, is_null: bool) -> Option<Self>

Safety

unsafe fn from_datum_in_memory_context( memory_context: PgMemoryContexts, datum: Datum, is_null: bool, typoid: Oid, ) -> Option<Self>

Default implementation switched to the specified memory context and then simply calls FromDatum::from_datum(...) from within that context.

unsafe fn try_from_datum( datum: Datum, is_null: bool, type_oid: Oid, ) -> Result<Option<Self>, TryFromDatumError>

where Self: IntoDatum,

try_from_datum is a convenience wrapper around FromDatum::from_datum that returns a a Result around an Option, as a Datum can be null. It’s intended to be used in situations where the caller needs to know whether the type conversion succeeded or failed.

unsafe fn try_from_datum_in_memory_context( memory_context: PgMemoryContexts, datum: Datum, is_null: bool, type_oid: Oid, ) -> Result<Option<Self>, TryFromDatumError>

where Self: IntoDatum,

A version of try_from_datum that switches to the given context to convert from Datum

impl IntoDatum for Cell

fn into_datum(self) -> Option<Datum>

fn type_oid() -> Oid

fn is_compatible_with(other: Oid) -> bool

Is a Datum of this type compatible with another Postgres type?

fn composite_type_oid(&self) -> Option<Oid>

impl Send for Cell
