I tried, but it doesn't work

I plan to build something like:

pub trait HttpSend<RequestBody>
where
    RequestBody: Body + 'static,
{
    type ResponseBody: Body + 'static;
    type Error: std::error::Error;

    fn send(
        &self,
        req: Request<RequestBody>,
    ) -> impl Future<Output = Result<Response<Self::ResponseBody>, Self::Error>> + Send;
}

But it failed for the very first step: reqwest:

impl<RequestBody> HttpSend<RequestBody> for Sender
where
    RequestBody: http_body::Body + 'static,
{
    type ResponseBody = reqwest::Body;
    type Error = reqwest::Error;

    async fn send(
        &self,
        req: http::Request<RequestBody>,
    ) -> Result<http::Response<Self::ResponseBody>, Self::Error> {
        // No way to convert `http_body::Body` into `reqwest::Body`
        Ok(self.0.execute(req.try_into()?).await?.into())
    }
}

We need seanmonstar/reqwest#2243
