Struct BatchValuesIteratorFromIterator

pub struct BatchValuesIteratorFromIterator<IT: Iterator> { /* private fields */ }

Implements BatchValuesIterator from an Iterator over references to things that implement SerializeRow

Essentially used internally by this lib to provide implementers of BatchValuesIterator for cases that always serialize the same concrete SerializeRow type

Trait Implementations

impl<'bv, 'sr: 'bv, IT, SR> BatchValuesIterator<'bv> for BatchValuesIteratorFromIterator<IT>

where IT: Iterator<Item = &'sr SR>, SR: SerializeRow + 'sr,

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.

fn is_empty_next(&mut self) -> Option<bool>

Returns whether the next set of values is empty or not and advances the iterator.

fn skip_next(&mut self) -> Option<()>

Skips the next set of values.

fn count(self) -> usize

where Self: Sized,

Return the number of sets of values, consuming the iterator in the process.

impl<IT> From<IT> for BatchValuesIteratorFromIterator<IT>

where IT: Iterator, IT::Item: SerializeRow,

fn from(it: IT) -> Self

Converts to this type from the input type.
