Fields

entity_value: Option<Entity>

An entity value.

• May have no key.
• May have a key with an incomplete key path.
• May have a reserved/read-only key.

timestamp_value: Option<String>

A timestamp value. When stored in the Datastore, precise only to microseconds; any additional precision is rounded down.

string_value: Option<String>

A UTF-8 encoded string value. When exclude_from_indexes is false (it is indexed) , may have at most 1500 bytes. Otherwise, may be set to at least 1,000,000 bytes.

double_value: Option<f64>

A double value.

meaning: Option<i32>

The meaning field should only be populated for backwards compatibility.

exclude_from_indexes: Option<bool>

If the value should be excluded from all indexes including those defined explicitly.

blob_value: Option<String>

A blob value. May have at most 1,000,000 bytes. When exclude_from_indexes is false, may have at most 1500 bytes. In JSON requests, must be base64-encoded.

key_value: Option<Key>

A key value.

boolean_value: Option<bool>

A boolean value.

array_value: Option<ArrayValue>

An array value. Cannot contain another array value. A Value instance that sets field array_value must not set fields meaning or exclude_from_indexes.

integer_value: Option<String>

An integer value.

geo_point_value: Option<LatLng>

A geo point value representing a point on the surface of Earth.

null_value: Option<String>

A null value.
