Code

I don't have an example yet; I'm pretty new to Rust. Given the output indicates that the entry_points::apigateway::create_token_set function is being type checked hopefully the following code snippets will be of assistance.

I do have another code base that I largely borrowed from where the signature is nearly the same other than the parameter being passed as &dyn (&dyn StorageService) now has an implementation that contains a Box (see code below).

use lambda_http::{http::StatusCode, IntoResponse, Request, RequestExt, Response};
use crate::clients::function::StorageService;

type E = Box<dyn std::error::Error + Send + Sync + 'static>;

pub async fn create_token_set(storage_service_client: &dyn StorageService,
                              request: Request) -> Result<impl IntoResponse, E> {
...
}

#[async_trait]
pub trait StorageService: Send + Sync {

    async fn store(&self, data: &PreAuthData) -> Result<TokenResult, Error>;

}
// is implemented by
pub struct StorageServiceClient {
    http_client: Client,
    service_discovery_client: Box<dyn ServiceDiscovery>
}


#[async_trait]
pub trait ServiceDiscovery: Send + Sync {
    async fn instances(&self, service_name: &str) -> Result<ServiceInstances, Error>;
}
// is implemented by
pub struct CloudMapClient {
    pub client: Client,
    pub namespace: String,
}


#[derive(Debug, Serialize)]
pub struct PreAuthData {
    #[serde(rename="ttlSeconds")]
    pub ttl_seconds: u64,
    pub data: HashMap<String, String>,
}

#[derive(Debug, Serialize, Deserialize)]
pub struct TokenResult {
    pub token: String,
}

Found code problems triggering the compiler issue. Below is the before and after snippets of the last code block of the create_token_set function. Note the changes on line 1 where there was a missing .await?, Line 2 now requiring the turbofish, and line 4 where the return value needed to be wrapped in Ok().

I note that the Intellij editor wasn't flagging these as errors/warnings even with the Clippy linter turned on. Actually the need for the turbofish was highlighted after fixing line 1.

let token_set = service::core::create_token_set(storage_service_client, session_id);
match serde_json::to_string(token_set) {
    Ok(token_set) => Ok(response(StatusCode::OK, token_set)),
    Err(_) => error_response(&InternalError(ConstMsg("Problem serializing response")))
}


let token_set = service::core::create_token_set(storage_service_client, session_id).await?;
match serde_json::to_string::<TokenSet>(&token_set) {
    Ok(token_set) => Ok(response(StatusCode::OK, token_set)),
    Err(error) => Ok(error_response(&InternalError(FormattedMsg(format!("Problem serializing response: {}", error)))))
}

This is a bug that will get fixed with the next release of rustc, I think!

I'm gonna close this since it's fixed (by #99928) which is now on stable.
