[−][src]Struct google_spanner1::KeySet
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.
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), Cloud Spanner behaves as if the key were only specified once.
This type is not used in any activity, and only used as part of another schema.
Fields
keys: Option<Vec<Vec<String>>>
A list of specific keys. Entries in keys
should have exactly as
many elements as there are columns in the primary or index key
with which this KeySet
is used. Individual key values are
encoded as described here.
ranges: Option<Vec<KeyRange>>
A list of key ranges. See KeyRange for more information about key range specifications.
all: Option<bool>
For convenience all
can be set to true
to indicate that this
KeySet
matches all keys in the table or index. Note that any keys
specified in keys
or ranges
are only yielded once.
