Struct Labels 

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

Owned metric label pairs for use with counter queries.

Provides a builder API and conversions from &[(&str, &str)] so callers can use either literal slices or the builder pattern.

Examples

use wireframe_testing::observability::Labels;

// Builder pattern
let labels = Labels::new()
    .with("error_type", "framing")
    .with("recovery_policy", "drop");

// From a literal array
let labels: Labels = [("error_type", "framing"), ("recovery_policy", "drop")].into();

Implementations

impl Labels

pub fn new() -> Self

Create an empty label set.

pub fn with(self, key: impl Into<String>, value: impl Into<String>) -> Self

Append a key-value pair, returning self for chaining.

Trait Implementations

impl Clone for Labels

fn clone(&self) -> Labels

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Labels

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

Formats the value using the given formatter.

impl Default for Labels

fn default() -> Labels

Returns the “default value” for a type.

impl From<&[(&str, &str)]> for Labels

fn from(pairs: &[(&str, &str)]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<&[(&str, &str); N]> for Labels

fn from(pairs: &[(&str, &str); N]) -> Self

Converts to this type from the input type.

impl<const N: usize> From<[(&str, &str); N]> for Labels

fn from(pairs: [(&str, &str); N]) -> Self

Converts to this type from the input type.

impl PartialEq for Labels

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