pub struct AnyArray { /* private fields */ }
Expand description
The anyarray
polymorphic pseudo-type.
Warning: Calling FromDatum::from_datum
with this type will unconditonally panic. Call
FromDatum::from_polymorphic_datum
with a type ID instead.

source§unsafe fn from_datum(_datum: Datum, _is_null: bool) -> Option<AnyArray>
unsafe fn from_datum(_datum: Datum, _is_null: bool) -> Option<AnyArray>
You should never call this function to make this type; it will unconditionally panic.
For polymorphic types such as this one, you must use FromDatum::from_polymorphic_datum
and pass a type ID.

unsafe fn from_polymorphic_datum( datum: Datum, is_null: bool, typoid: Oid ) -> Option<AnyArray>
Like
from_datum
for instantiating polymorphic types
which require preserving the dynamic type metadata. Read moresource§unsafe fn from_datum_in_memory_context(

unsafe fn from_datum_in_memory_context( memory_context: PgMemoryContexts, datum: Datum, is_null: bool, typoid: Oid ) -> Option<Self>where Self: Sized,
Default implementation switched to the specified memory context and then simply calls
FromDatum::from_datum(...)
from within that context. Read moresource§unsafe fn try_from_datum(
datum: Datum,
is_null: bool,
type_oid: Oid
) -> Result<Option<Self>, TryFromDatumError>where

unsafe fn try_from_datum( datum: Datum, is_null: bool, type_oid: Oid ) -> Result<Option<Self>, TryFromDatumError>where Self: Sized + 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. Read moresource§unsafe fn try_from_datum_in_memory_context(
memory_context: PgMemoryContexts,
datum: Datum,
is_null: bool,
