Trait WithRequestContext 

pub trait WithRequestContext {
    // Required method
    fn with_request_context(self, uri: &Uri) -> Self;
}

Middleware-friendly: enrich errors from Axum extractors

Use this in handlers to automatically add trace context:

async fn handler(uri: Uri) -> Result<Json<Data>, Problem> {
    let data = fetch_data()
        .await
        .map_err(Problem::from)
        .map_err(|p| p.with_request_context(&uri))?;
    Ok(Json(data))
}

Required Methods

fn with_request_context(self, uri: &Uri) -> Self

Add trace_id and instance from the current request

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
