Struct opentelemetry::KeyValue

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

KeyValue pairs are used by LabelSets 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

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

Performs copy-assignment from source.

impl Debug for KeyValue

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

Formats the value using the given formatter.

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

pub fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,
