    // Required methods
    fn new_empty() -> Self;
    fn load_put<P>(

}

A type that may or may not be a DataPayload and may or may not contain a value depending on the type parameter Variables.

Helper trait for DateTimeNamesMarker.

Required Methods

fn new_empty() -> Self

fn load_put<P>( &mut self, provider: &P, req: DataRequest<'_>, variables: Variables, ) -> Result<Result<(), DataError>, MaybePayloadError>

where P: BoundDataProvider<M> + ?Sized, Self: Sized,

fn get(&self) -> DataPayloadWithVariablesBorrowed<'_, M, Variables>

Object Safety
