Struct opentelemetry_sdk::metrics::AttributeSet

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

A unique set of attributes that can be used as instrument identifiers.

This must implement Hash, PartialEq, and Eq so it may be used as HashMap keys and other de-duplication methods.

Implementations

impl AttributeSet

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

pub fn retain<F>(&mut self, f: F)

where F: Fn(&KeyValue) -> bool,

Retains only the attributes specified by the predicate.

pub fn iter(&self) -> impl Iterator<Item = (&Key, &Value)>

Iterate over key value pairs in the set

Trait Implementations

impl Clone for AttributeSet

fn clone(&self) -> AttributeSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeSet

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

Formats the value using the given formatter.

impl Default for AttributeSet

fn default() -> AttributeSet

Returns the “default value” for a type.

impl From<&[KeyValue]> for AttributeSet

fn from(values: &[KeyValue]) -> Self

Converts to this type from the input type.

impl Hash for AttributeSet

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 AttributeSet

fn eq(&self, other: &AttributeSet) -> 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 Eq for AttributeSet

impl StructuralPartialEq for AttributeSet
