wasm_bindgen Rust 中的异步 fn 问题

问：

所以我挣扎了一段时间，因为 Rust 编译器不会给我关于这个问题的足够信息。

我尝试将 Rust 库编译成 wasm 模块，但每次我尝试编译它都会给我这个错误：wasm-pack build --out-dir [dir]

error[E0597]: `*arg0` does not live long enough
  --> src/lib.rs:10:1
   |
10 | #[wasm_bindgen]
   | ^^^^^^^^^^^^^^-
   | |             |
   | |             `*arg0` dropped here while still borrowed
   | borrowed value does not live long enough
   | argument requires that `*arg0` is borrowed for `'static`

error: aborting due to previous error

法典：

use wasm_bindgen::prelude::*;
use wasm_bindgen_futures::JsFuture;
use js_sys;

#[wasm_bindgen]
pub async fn calculation(x:i32,y:i32) -> Result<JsValue,JsValue>{
    let f = js_sys::Promise::resolve(&JsValue::from_str("Mama"));
    let p = wasm_bindgen_futures::JsFuture::from(f).await?;
    Ok((p))
}


#[wasm_bindgen]
pub async fn picture_calculation(picture: &[u8]) -> JsValue{

    JsValue::from_str("Hello")
}
