Implementations

impl NullValue

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of NullValue.

pub fn from_i32(value: i32) -> Option<NullValue>

Converts an i32 to a NullValue, or None if value is not a valid variant.

impl NullValue

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

Trait Implementations

impl Clone for NullValue

fn clone(&self) -> NullValue

Returns a copy 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<'de> Deserialize<'de> for NullValue

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<()> for NullValue

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<NullValue> for i32

fn from(value: NullValue) -> i32

Converts to this type from the input type.

impl Hash for NullValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl Ord for NullValue

fn cmp(&self, other: &NullValue) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<NullValue> for NullValue

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

impl PartialOrd<NullValue> for NullValue

fn partial_cmp(&self, other: &NullValue) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for NullValue

fn serialize<S>(&self, ser: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for NullValue

impl StructuralEq for NullValue
