Struct KeyValue

pub struct KeyValue<'a> {
    pub key: Cow<'a, str>,
    pub value: Value<'a>,
}

A key-value attribute pair used in telemetry data.

Key-value pairs provide additional context for spans, events, and log messages. The key is typically a string identifier, and the value can be one of several supported data types.

Examples

use veecle_telemetry::types::StringType;
use veecle_telemetry::{KeyValue, Value};

// Create attributes with different value types
let user_id = KeyValue::new("user_id", 123);
let username = KeyValue::new("username", "alice");
let is_active = KeyValue::new("is_active", true);
let score = KeyValue::new("score", 95.5);

Fields

key: Cow<'a, str>

The attribute key (name)

value: Value<'a>

The attribute value

Implementations

impl<'a> KeyValue<'a>

pub fn new<K, V>(key: K, value: V) -> KeyValue<'a>

where K: Into<Cow<'a, str>>, V: Into<Value<'a>>,

Creates a new key-value attribute pair.

Arguments

• key - The attribute key (name)
• value - The attribute value

Examples

use veecle_telemetry::KeyValue;

let user_id = KeyValue::new("user_id", 123);
let username = KeyValue::new("username", "alice");

Trait Implementations

impl<'a> Clone for KeyValue<'a>

fn clone(&self) -> KeyValue<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for KeyValue<'a>

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

Formats the value using the given formatter.

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

where 'de: 'a,

fn deserialize<__D>( __deserializer: __D, ) -> Result<KeyValue<'a>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Serialize for KeyValue<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToStatic for KeyValue<'_>

type Static = KeyValue<'static>

The same type but with ’static lifetime and owned data.

fn to_static(&self) -> <KeyValue<'_> as ToStatic>::Static

Converts this type to the equivalent type with ’static lifetime.
