Actix Request Identifier Middleware

actix-request-identifier implements a middleware for actix-web that generates an ID for each incomming request. By default, a UUID v4 is generated for each request using uuid. The request ID is set via the x-request-id HTTP header (which can be configured) and can be extracted from the request using RequestId.

Example

```rust use actixrequestidentifier::{RequestId, RequestIdentifier};

[get("/")]

async fn index(id: RequestId) -> impl Responder { HttpResponse::Ok().body(format!("{}", id.as_str())) }

[actix_rt::main]

async fn main() { HttpServer::new(move || { App::new() .wrap(RequestIdentifier::with_uuid()) .service(index) }).bind("127.0.0.1:8080") .unwrap() .run() .await .unwrap(); ```

The response looks like this:

``` $ curl -i 127.0.0.1:8080/ HTTP/1.1 200 OK content-length: 36 x-request-id: 5f099854-2117-49b3-b252-d6693a85acc5 date: Mon, 20 Apr 2020 06:53:49 GMT
