actix-web-correlation-id

An Actix-web middleware component which synchronises a correlation ID for cross API request logging

Example:

```rust use actixweb::{ client::Client, middleware::Logger, web::{self}, App, Error, HttpResponse, HttpServer, }; use actixwebcorrelationid::{ Correlation, CorrelationId, CorrelationIdPropagate, CorrelationIdVariable, };

async fn index(corr_id: CorrelationId) -> Result { let client = Client::new();

let mut res = client
    .get("http://google.com/")
    .with_corr_id(corr_id)
    .send()
    .await?;

let mut client_resp = HttpResponse::build(res.status());

Ok(client_resp.body(res.body().await?))

}

[actix_web::main]

async fn main() -> std::io::Result<()> { envlogger::initfromenv(envlogger::Env::new().defaultfilteror("info"));

HttpServer::new(move || {
    App::new()
        .wrap(
            Logger::new("%{corr-id}xi %a \"%r\" %s %b \"%{Referer}i\" \"%{User-Agent}i\" %T")
                .add_corr_id(),
        )
        .wrap(
            Correlation::new()
                .header_name("x-correlation-id")
                .enforce_header(false)
                .resp_header_name(Some("x-correlation-id"))
                .include_in_resp(true),
        )
        .service(web::resource("/simple").route(web::post().to(index)))
})
.bind("127.0.0.1:8080")?
.run()
.await

} ```
