source · pub trait BatchValuesIterator<'bv> {
// Required methods
fn serialize_next(
&mut self,
ctx: &RowSerializationContext<'_>,
writer: &mut RowWriter<'_>,
) -> Option<Result<(), SerializationError>>;

where Self: Sized { ... }
}Expand description
An Iterator-like object over the values from the parent BatchValues object.
It’s not a true Iterator because it does not provide direct access to the
items being iterated over, instead it allows calling methods of the underlying
SerializeRow trait while advancing the iterator.
Required Methods§
sourcefn serialize_next(
&mut self,
ctx: &RowSerializationContext<'_>,
writer: &mut RowWriter<'_>,
) -> Option<Result<(), SerializationError>>
fn serialize_next( &mut self, ctx: &RowSerializationContext<'_>, writer: &mut RowWriter<'_>, ) -> Option<Result<(), SerializationError>>
Serializes the next set of values in the sequence and advances the iterator.
sourcefn is_empty_next(&mut self) -> Option<bool>
fn is_empty_next(&mut self) -> Option<bool>
Returns whether the next set of values is empty or not and advances the iterator.
