[−][src]Struct google_datastore1_beta3::Key
A unique identifier for an entity. If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts.
This type is not used in any activity, and only used as part of another schema.
Fields
path: Option<Vec<PathElement>>
The entity path. An entity path consists of one or more elements composed of a kind and a string or numerical identifier, which identify entities. The first element identifies a root entity, the second element identifies a child of the root entity, the third element identifies a child of the second entity, and so forth. The entities identified by all prefixes of the path are called the element's ancestors.
An entity path is always fully complete: all of the entity's ancestors
are required to be in the path along with the entity identifier itself.
The only exception is that in some documented cases, the identifier in the
last path element (for the entity) itself may be omitted. For example,
the last path element of the key of Mutation.insert
may have no
identifier.
A path can never be empty, and a path can have at most 100 elements.
partition_id: Option<PartitionId>
Entities are partitioned into subsets, currently identified by a project ID and namespace ID. Queries are scoped to a single partition.
