Is there a Rust crate or Cargo upgrade that can format imports?

Question

Is there a way to optimize and format all crate imports in scope, to clean up the imports sections? The problem is that the imports get crowded and stack up.

Before:

use actix_web::web::{Data, Payload};
use actix_web::Error;
use actix_web::{
    error::{BlockingError, ErrorUnauthorized},
    web, HttpResponse,
};

After:

use actix_web::{web::
                {Data, Payload},
                Error,
                error::{BlockingError, ErrorUnauthorized},
                web, HttpResponse,
};

Actually rustfmt can do this. Create a rustfmt.toml configuration file in your project directory and specify the following:

merge_imports = true

The rustfmt has more configurable options if you are interested.
