Struct NullValue

pub struct NullValue;

The Google Cloud APIs use google.protobuf.NullValue to represent JSON null values.

The Google Cloud client libraries for Rust map google.protobuf.NullValue to this unit type.

Implementations

impl NullValue

pub fn value(&self) -> Option<i32>

Gets the value.

pub fn name(&self) -> Option<&str>

Gets the value as a string.

Trait Implementations

impl Clone for NullValue

fn clone(&self) -> NullValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullValue

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

Formats the value using the given formatter.

impl Default for NullValue

fn default() -> NullValue

Returns the “default value” for a type.

impl From<&NullValue> for Value

fn from(_value: &NullValue) -> Self

Converts to this type from the input type.

impl From<&str> for NullValue

fn from(_value: &str) -> Self

Converts to this type from the input type.

impl From<NullValue> for Value

fn from(_value: NullValue) -> Self

Converts to this type from the input type.

impl From<NullValue> for i32

fn from(_value: NullValue) -> Self

Converts to this type from the input type.

impl From<String> for NullValue

fn from(_value: String) -> Self

Converts to this type from the input type.

impl From<i32> for NullValue

fn from(_value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for NullValue

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

Tests for self and other values to be equal, and is used by ==.

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

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