Struct metrics_core::Label

pub struct Label(_, _);

A key/value pair used to further describe a metric.

Methods

impl Label

pub fn new<K, V>(key: K, value: V) -> Self where
    K: Into<ScopedString>,
    V: Into<ScopedString>, 

Creates a Label from a key and value.

pub fn key(&self) -> &str

The key of this label.

pub fn value(&self) -> &str

The value of this label.

pub fn into_parts(self) -> (ScopedString, ScopedString)

Consumes this Label, returning the key and value.

Trait Implementations

impl<K, V> From<(K, V)> for Label where
    K: Into<ScopedString>,
    V: Into<ScopedString>, 

fn from(pair: (K, V)) -> Label

Performs the conversion.

impl<'_, K, V> From<&'_ (K, V)> for Label where
    K: Into<ScopedString> + Clone,
    V: Into<ScopedString> + Clone, 

fn from(pair: &(K, V)) -> Label

Performs the conversion.

impl Clone for Label

fn clone(&self) -> Label

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for Label

impl PartialEq<Label> for Label

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

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

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

This method tests for !=.

impl Debug for Label

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

Formats the value using the given formatter.

impl Hash for Label

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].
