Extract and inject W3C TraceContext headers.
§Examples
let mut headers = http::HeaderMap::new();
headers.insert(
"traceparent",
"00-0af7651916cd43dd8448eb211c80319c-00f067aa0ba902b7-01".parse().unwrap()
);
let context = trace_context::TraceContext::extract(&headers).unwrap();
assert_eq!(context.trace_id(), u128::from_str_radix("0af7651916cd43dd8448eb211c80319c", 16).unwrap());
assert_eq!(context.parent_id(), u64::from_str_radix("00f067aa0ba902b7", 16).ok());
assert_eq!(context.sampled(), true);
