Struct scylla::frame::value::LegacyBatchValuesFirstSerialized
source · 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
