Struct KeySet

pub struct KeySet {
    pub all: Option<bool>,
    pub keys: Option<Vec<Vec<Value>>>,
    pub ranges: Option<Vec<KeyRange>>,
}

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

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.

keys: Option<Vec<Vec<Value>>>

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.
