tower-http-tracing

Tower tracing middleware to annotate every HTTP request with tracing's span

Example

Below is illustration of how to initialize request layer for passing into your service

use std::net::IpAddr;

use tower_http_tracing::HttpRequestLayer;

//Logic to extract client ip has to be written by user
//You can use utilities in separate crate to design this logic:
//https://docs.rs/http-ip/latest/http_ip/
fn extract_client_ip(_parts: &http::request::Parts) -> Option<IpAddr> {
    None
}
tower_http_tracing::make_request_spanner!(make_my_request_span("my_request", tracing::Level::INFO));
let layer = HttpRequestLayer::new(make_my_request_span).with_extract_client_ip(extract_client_ip)
                                                       .with_inspect_headers(&[&http::header::FORWARDED]);
//Use above layer in your service
