rocket receive file

[wotori]

Hello everyone!
How can I save process file that I have just received?
I found that I can use rocket::{Data} but how to stream this file into save function of for example ipfs method?

#[openapi(tag = "ipfs")]
#[post("/", data = "<paste>")]
pub async fn upload_file(
    paste: Data<'_>,
) -> String {
    let client = IpfsClient::default();
    let file = File::open(paste).await;
    println!("saving file...");
    match client.add(file).await {
        Ok(res) => res.hash.clone(),
        Err(_e) => String::from("error")
    }
}

got this error

22 |     match client.add(media).await {
   |                  --- ^^^^^ the trait `std::io::Read` is not implemented for `rocket::Data<'_>`
   |                  |

I read documentation more carefully and found that things are more difficult that it seems to be for the first time.
