Struct KeyValue 

pub struct KeyValue<'a, F>
where
    F: StorageFamily + 'a,
{
    pub key: <F as StorageFamily>::String<'a>,
    pub value: <F as StorageFamily>::Value<'a>,
}

A key-value attribute pair used in telemetry data.

Key-value pairs provide additional context for spans, events, and log messages.

Examples

use veecle_telemetry::protocol::transient::KeyValue;

// 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: <F as StorageFamily>::String<'a>

The attribute key (name).

value: <F as StorageFamily>::Value<'a>

The attribute value.

Implementations

impl<'a, F> KeyValue<'a, F>

where F: StorageFamily + 'a,

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

where K: Into<<F as StorageFamily>::String<'a>>, V: Into<<F as StorageFamily>::Value<'a>>,

Creates a new key-value attribute pair.

Arguments

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

Examples

use veecle_telemetry::protocol::transient::KeyValue;

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