Methods for sorting and retrieving baggage data in a context.

Required methods

fn current_with_baggage<T: IntoIterator<Item = KeyValue>>(baggage: T) -> Self

Returns a clone of the current context with the included name / value pairs.

Examples

use opentelemetry::api::{BaggageExt, Context, KeyValue, Value};

let cx = Context::current_with_baggage(vec![KeyValue::new("my-name", "my-value")]);

assert_eq!(
    cx.baggage().get("my-name"),
    Some(&Value::String("my-value".to_string())),
)

fn with_baggage<T: IntoIterator<Item = KeyValue>>(&self, baggage: T) -> Self

Returns a clone of the given context with the included name / value pairs.

Examples

use opentelemetry::api::{BaggageExt, Context, KeyValue, Value};

let some_context = Context::current();
let cx = some_context.with_baggage(vec![KeyValue::new("my-name", "my-value")]);

assert_eq!(
    cx.baggage().get("my-name"),
    Some(&Value::String("my-value".to_string())),
)

fn with_cleared_baggage(&self) -> Self

Returns a clone of the given context with the included name / value pairs.

Examples

use opentelemetry::api::{BaggageExt, Context, KeyValue, Value};

let cx = Context::current().with_cleared_baggage();

assert_eq!(cx.baggage().len(), 0);

fn baggage(&self) -> &Baggage

Returns a reference to this context's baggage, or the default empty baggage if none has been set.
