pub struct LabelName(/* private fields */);

Implementations

impl LabelName

pub fn new(name: &str) -> Self

Creates a new LabelName instance.

Panics

Panics if the provided name is empty.

Trait Implementations

impl Clone for LabelName

fn clone(&self) -> LabelName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LabelName

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

Formats the value using the given formatter.

impl Default for LabelName

fn default() -> LabelName

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LabelName

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LabelName

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

Formats the value using the given formatter.

impl Eq for LabelName

impl Hash for LabelName

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for LabelName

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LabelName

fn eq(&self, other: &LabelName) -> 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 PartialOrd for LabelName

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl PrometheusSerializable for LabelName

fn to_prometheus(&self) -> String

In Prometheus:

• Labels may contain ASCII letters, numbers, as well as underscores. They must match the regex [a-zA-Z_][a-zA-Z0-9_]*.
• Label names beginning with __ (two “_”) are reserved for internal use.
• Label values may contain any Unicode characters.
• Labels with an empty label value are considered equivalent to labels that do not exist.

The label name is changed:

• If a label name starts with, or contains, an invalid character: replace character with underscore.
• If th label name starts with two underscores: add additional underscore (three underscores total)

impl Serialize for LabelName

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
