Struct opentelemetry::labels::LabelSet

pub struct LabelSet { /* fields omitted */ }

This is supported on crate feature metrics only.

An immutable set of distinct labels.

Implementations

impl LabelSet

pub fn from_labels<T: IntoIterator<Item = KeyValue>>(labels: T) -> Self

Construct a new label set form a distinct set of labels

pub fn len(&self) -> usize

The label set length.

pub fn is_empty(&self) -> bool

Check if the set of labels is empty.

pub fn iter(&self) -> Iter<'_>

Iterate over the label key value pairs.

pub fn encoded(&self, encoder: Option<&dyn Encoder>) -> String

Encode the label set with the given encoder and cache the result.

Trait Implementations

impl Clone for LabelSet

fn clone(&self) -> LabelSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LabelSet

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

Formats the value using the given formatter.

impl Default for LabelSet

fn default() -> LabelSet

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a LabelSet

type Item = (&'a Key, &'a Value)

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
