Tokio 1.0 – async runtime for Rust

Re:Tokio 1.0 – async runtime for Rust by jayy-lmao on Wednesday December 23, 2020 @07:21PM (#25523874)

I've got a few examples of simple web servers within my company, could backport some of it to a public example. Are you just looking to have something a bit like: ``` #[get('/todo')] async fn getTodos(...) -> impl Responder { let todos = reqwest.get('other-api/todos').await?;

  todos

} ```

Obviously this code won't run, just want to gleam the gist of what you want from an example.

Hey, thank you for offering. Yes! Something minimal like that that doesn't use `reqwest::blocking` would be very helpful.

If it could do the Error case too that would be cool.

For Rocket, I have something like:

    #[get("/list/<status>")]
    fn list_prospects(api_key: ApiKey, status: String) -> Result<Json<PendingList>, Status>

with a

    impl<'a, 'r> FromRequest<'a, 'r> for ApiKey

But I couldn't quickly get an `async` piece in there so I just sucked it up and synced it all up since it's only backing a Retool dashboard so it isn't the end of the world.

So if the example is like:

    #[get('/todo')]
    fn get_todos() -> Result<Json<TodoList>, Status>
      let todos = reqwest...
      Ok(todos)

or the equivalent in the web framework you have that would be hecka useful.

For Rocket you want to use the master branch which has async support. Then your request handler is an async function and you can just .await the future returned by reqwest.

Oh, I must be behind. Should've kept up and tried it. Thank you!
