Must have a value set.

Variants

NullValue(i32)

A null value.

BooleanValue(bool)

A boolean value.

IntegerValue(i64)

An integer value.

DoubleValue(f64)

A double value.

TimestampValue(Timestamp)

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

KeyValue(Key)

A key value.

StringValue(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 most 1,000,000 bytes.

BlobValue(Bytes)

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.

GeoPointValue(LatLng)

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

EntityValue(Entity)

An entity value.

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

ArrayValue(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.

Implementations

impl ValueType

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<ValueType>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext ) -> Result<(), DecodeError>

where B: Buf,

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for ValueType

fn clone(&self) -> ValueType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ValueType

fn eq(&self, other: &ValueType) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
