Member Function Documentation

template<typename T , typename = void>

static T cppgres::datum_conversion< T, typename >::from_datum	(	const datum &	,
		const	oid,
		std::optional< memory_context >	context = `std::nullopt`
	)

staticdelete

Convert from a datum.

Gets an optional cppgres::memory_context when available to be able to determine the source of the (pointer) datum.

template<typename T , typename = void>

static T cppgres::datum_conversion< T, typename >::from_nullable_datum	(	const nullable_datum &	d,
		const oid	oid,
		std::optional< memory_context >	context = `std::nullopt`
	)

staticdelete

Convert from a nullable datum.

Gets an optional cppgres::memory_context when available to be able to determine the source of the (pointer) datum.

template<typename T , typename = void>

static datum cppgres::datum_conversion< T, typename >::into_datum ( const T & d )

staticdelete

Convert datum into a type.

Unlike from_datum, gets no memory context.
