reqwest-tracing

Opentracing middleware implementation for reqwest-middleware.

Overview

Attach TracingMiddleware to your client to automatically trace HTTP requests:

use opentelemetry::exporter::trace::stdout;
use reqwest_middleware::ClientBuilder;
use reqwest_tracing::TracingMiddleware;
use tracing_subscriber::layer::SubscriberExt;
use tracing_subscriber::Registry;

#[tokio::main]
async fn main() {
  let (tracer, _) = stdout::new_pipeline().install();
  let telemetry = tracing_opentelemetry::layer().with_tracer(tracer);
  let subscriber = Registry::default().with(telemetry);
  tracing::subscriber::set_global_default(subscriber).unwrap();

  run().await;
}

async fun run() {
  let client = ClientBuilder::new(reqwest::Client::new())
    .with(TracingMiddleware)
    .build();`

  client.get("https://truelayer.com").send().await.unwrap();
}

See the tracing crate for more information on how to set up a tracing subscriber to make use of the spans.

How to install

Add reqwest-tracing to your dependencies. Optionally enable opentelemetry integration by enabling an opentelemetry version feature:

[dependencies]
# ...
reqwest-tracing = { version = "0.1.0", features = ["opentelemetry_0_16"] }

Available opentelemetry features are opentelemetry_0_16, opentelemetry_0_15, opentelemetry_0_14 and opentelemetry_0_13.
