Struct tracing_actix_web::RootSpan

pub struct RootSpan(_);

The root span associated to the in-flight current request.

It can be used to populate additional properties using values computed or retrieved in the request handler - see the crate-level documentation for more details.

Extracting a RootSpan when the TracingLogger middleware is not registered will result in an internal server error.

Usage

use actix_web::get;
use tracing_actix_web::RootSpan;
use uuid::Uuid;

#[get("/")]
async fn index(root_span: RootSpan) -> String {
    root_span.record("route", &"/");
}
