Struct KeyValue 

pub struct KeyValue<'a> {
    pub key: StringType<'a>,
    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: StringType<'a>

The attribute key (name)

value: Value<'a>

The attribute value

Implementations

impl<'a> KeyValue<'a>

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

where K: Into<StringType<'a>>, 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");
