error: future cannot be sent between threads safely

[wotori]

Hi!
I am trying to create an API just for pining a files.
What I currently have:

#[openapi(tag = "ipfs")]
#[post("/")]
pub async fn upload_file() -> String {
    let client = IpfsClient::default();
    let file = Cursor::new("Hello, world!");
    match client.add(file).await {
        Ok(res) => res.hash,
        Err(e) => String::from("error")
    }
}

and this follows with error:

 cargo check
    Checking ipfs-api v0.0.1 (/Users/wotori/git/wotori/ipfs-api)
error: future cannot be sent between threads safely
  --> src/test_routes.rs:8:1
   |
8  | #[post("/")]
   | ^^^^^^^^^^^^ future created by async block is not `Send`
   |
   = help: the trait `std::marker::Send` is not implemented for `dyn std::future::Future<Output = Result<AddResponse, ipfs_api_backend_hyper::Error>>`
note: future is not `Send` as it awaits another future which is not `Send`
  --> src/test_routes.rs:12:11
   |
12 |     match client.add(file).await {
   |           ^^^^^^^^^^^^^^^^ await occurs here on type `Pin<Box<dyn std::future::Future<Output = Result<AddResponse, ipfs_api_backend_hyper::Error>>>>`, which is not `Send`
   = note: required for the cast to the object type `dyn std::future::Future<Output = Outcome<rocket::Response<'__r>, Status, rocket::Data<'__r>>> + std::marker::Send`
   = note: this error originates in the attribute macro `post` (in Nightly builds, run with -Z macro-backtrace for more info)

error: could not compile `ipfs-api` due to previous error

Smth does not implemented yet in rust-ipfs-api or I am doing smth terribly wrong?

Found the answer in discord, tnx for the rust community!
Just need to add "with-send-sync"
ipfs-api-backend-hyper = { version = "your version", features = ["with-send-sync"] }
