pub enum ValueMode {
Exclusive,
Cluster,
Replace,
}
Expand description
Define the behavior of the index in case a key value pair already exists
Variants
Exclusive
An error will return if a key value pair already exists
Cluster
The value will be add to a list of values for the key, duplicate value will be collapsed to only one entry
Replace
The existing value will be replaced with the new value if a key value pair already exists
