Struct Label

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

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

Implementations

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 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 Debug for Label

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

Formats the value using the given formatter.

impl<K, V> From<&(K, V)> for Label

where K: Into<ScopedString> + Clone, V: Into<ScopedString> + Clone,

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

Converts to this type from the input type.

impl<K, V> From<(K, V)> for Label

where K: Into<ScopedString>, V: Into<ScopedString>,

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

Converts to this type from the input type.

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Label

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