Struct LabelValue

#[non_exhaustive]
pub struct LabelValue {
    pub value: Option<Value>,
}

A label value.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

value: Option<Value>

The label value can be a bool, int64, or string.

Implementations

impl LabelValue

pub fn set_value<T: Into<Option<Value>>>(self, v: T) -> Self

Sets the value of value.

pub fn get_bool_value(&self) -> Option<&bool>

The value of value if it holds a BoolValue, None if the field is not set or holds a different branch.

pub fn get_int64_value(&self) -> Option<&i64>

The value of value if it holds a Int64Value, None if the field is not set or holds a different branch.

pub fn get_string_value(&self) -> Option<&String>

The value of value if it holds a StringValue, None if the field is not set or holds a different branch.

pub fn set_bool_value<T: Into<bool>>(self, v: T) -> Self

Sets the value of value to hold a BoolValue.

Note that all the setters affecting value are mutually exclusive.

pub fn set_int64_value<T: Into<i64>>(self, v: T) -> Self

Sets the value of value to hold a Int64Value.

Note that all the setters affecting value are mutually exclusive.

pub fn set_string_value<T: Into<String>>(self, v: T) -> Self

Sets the value of value to hold a StringValue.

Note that all the setters affecting value are mutually exclusive.

Trait Implementations

impl Clone for LabelValue

fn clone(&self) -> LabelValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LabelValue

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

Formats the value using the given formatter.

impl Default for LabelValue

fn default() -> LabelValue

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LabelValue

where LabelValue: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for LabelValue

fn typename() -> &'static str

The typename of this message.

impl PartialEq for LabelValue

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

impl Serialize for LabelValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
