Struct scylla_cql::frame::value::LegacyBatchValuesFirstSerialized

pub struct LegacyBatchValuesFirstSerialized<'f, T> { /* private fields */ }

👎Deprecated since 0.15.1: Legacy serialization API is not type-safe and is going to be removed soon

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
