pub struct LegacyBatchValuesFirstSerialized<'f, T> { /* private fields */ }Expand description
Allows reusing already-serialized first value
We’ll need to build a LegacySerializedValues for the first ~ValueList of a batch to figure out the shard (#448).
Once that is done, we can use that instead of re-serializing.
This struct implements both BatchValues and BatchValuesIterator for that purpose
