dd-trace-layer

dd-trace-layer is a middleware for sending Datadog's trace. It's based on Tower and OpenTelemetry Rust.

Usage

This can be used in hyper or axum, etc. See examples.

```rust use ddtracelayer::{init, ApiVersion, DDTraceLayer}; use hyper::{server::Server, Body, Error, Request, Response}; use std::net::SocketAddr; use tower::{make::Shared, ServiceBuilder};

[tokio::main]

async fn main() { init("service_name", "http://localhost:8126", ApiVersion::Version05);

let service = ServiceBuilder::new()
    .layer(DDTraceLayer::new("operation_name".to_string()))
    .service_fn(hello_world);

let addr = SocketAddr::from(([127, 0, 0, 1], 8080));
Server::bind(&addr)
    .serve(Shared::new(service))
    .await
    .expect("server error");

}

async fn helloworld(: Request) -> Result, Error> { Ok(Response::new(Body::from("Hello, World!"))) } ```
