Attempting to import `reqwest::async` errors stating that `async` is a reserved keyword

I want to make asynchronous HTTP requests using the reqwest crate. I have the following code:

// see https://docs.rs/reqwest/*/reqwest/async/index.html
use reqwest::async::Client;

When I attempt to compile my code I get the following error:

error: expected identifier, found reserved keyword `async`
 --> src/main.rs:1:14
  |
1 | use reqwest::async::Client;
  |              ^^^^^ expected identifier, found reserved keyword

How do I import from the async module?

Solution

  • Since reqwest::async was created before async was a reserved keyword (which happened in Rust 2018, I believe) previously this Just Worked™.

    Now that async is a reserved keyword you need to use the raw identifier syntax:

    use request::r#async::Client;
