Module http_types::trace

This is supported on unstable only.

Extract and inject trace context headers.

Examples

use http_types::trace::TraceContext;

let mut res = http_types::Response::new(200);

res.insert_header(
    "traceparent",
    "00-0af7651916cd43dd8448eb211c80319c-00f067aa0ba902b7-01"
);

let context = TraceContext::extract(&res).unwrap();

let trace_id = u128::from_str_radix("0af7651916cd43dd8448eb211c80319c", 16);
let parent_id = u64::from_str_radix("00f067aa0ba902b7", 16);

assert_eq!(context.trace_id(), trace_id.unwrap());
assert_eq!(context.parent_id(), parent_id.ok());
assert_eq!(context.sampled(), true);
