Actix Web HTTP Client is not working?

help
1

Hi everyone,

I'm trying to get the Actix Web Client to compile, as per the documentation:

https://actix.rs/api/actix-web/stable/actix_web/client/index.html

use actix_web::{actix, client};

fn main() {
    actix::run(
        || client::get("http://www.rust-lang.org")   // <- Create request builder
            .header("User-Agent", "Actix-web")
            .finish().unwrap()
            .send()                               // <- Send http request
            .map_err(|_| ())
            .and_then(|response| {                // <- server http response
                println!("Response: {:?}", response);
                Ok(())
            })
    );
}

However, I get an error I cannot seem to work around:

no method named map_err found for type actix_web::client::SendRequest in the current scope

help: items from traits can only be used if the trait is in scope

What am I doing wrong? Is the documention not correct any more?

You need to import Future to use map_err

Yes, that solved it! Thank you, perhaps it should be added to the code in the documentation as well?

4

Yeah, it probably should

5

Nomally compiler tells you to import Future

6

I'm using VS Code with RLS - could that be the reason why it didn't tell anything to me?

Yes, maybe rls isn't as good as the compiler on error messages

8

These messages are done on a best effort basis, so the compiler may have just missed Future as a possibility.
