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

which require preserving the dynamic type metadata. Read moresource§const GET_TYPOID: bool = false

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(

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(
