SetTraceIdLayer

Struct SetTraceIdLayer

pub struct SetTraceIdLayer<T>where
    T: MakeTraceId,
{ /* private fields */ }

Expand description

Add the TraceId extension to requests and optionally include trace ids in request and response headers.

use std::convert::Infallible;
use hyper::{Body, Request, Response};
use tower::ServiceBuilder;
use hyper_trace_id::{SetTraceIdLayer, TraceId};

let trace_id_header = "x-trace-id";
let svc = ServiceBuilder::new()
    .layer(SetTraceIdLayer::<String>::new().with_header_name(trace_id_header))
    .service_fn(|_req: Request<Body>| async {
        let res: Result<Response<Body>, Infallible> = Ok(Response::new(Body::empty()));
        res
    });
