Struct KeyValue

pub struct KeyValue {
    pub key: Key,
    pub value: Value,
}

KeyValue pairs are used by AttributeSets and Span attributes.

Fields

key: Key

Dimension or event key

value: Value

Dimension or event value

Implementations

impl KeyValue

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

where K: Into<Key>, V: Into<Value>,

Create a new KeyValue pair.

Trait Implementations

impl Clone for KeyValue

fn clone(&self) -> KeyValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<KeyValue> for KeyValueMetadata

fn from(kv: KeyValue) -> Self

Converts to this type from the input type.

impl FromIterator<KeyValue> for Baggage

fn from_iter<I: IntoIterator<Item = KeyValue>>(iter: I) -> Self

Creates a value from an iterator.

impl PartialEq for KeyValue

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

Tests for self and other values to be equal, and is used by ==.

const 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 Serialize for KeyValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
