Struct google_cloud_spanner::key::KeySet

pub struct KeySet { /* private fields */ }

/ A KeySet defines a collection of Cloud Spanner keys and/or key ranges. All / the keys are expected to be in the same table or index. The keys need not be / sorted in any particular way. / / An individual Key can act as a KeySet, as can a KeyRange. Use the KeySets / function to create a KeySet consisting of multiple Keys and KeyRanges. To / obtain an empty KeySet, call KeySets with no arguments. / / If the same key is specified multiple times in the set (for example if two / ranges, two keys, or a key and a range overlap), the Cloud Spanner backend / behaves as if the key were only specified once.
