Is it possible to set a body for an IntoResponses enum?

[rster2002]

Hi!

I was wondering if it's possible for an enum that derives IntoResponses to specify a body for the whole enum (or per variant for that matter). For example, I have the following enum:

use displaydoc::Display;
use thiserror::Error;
use utoipa_gen::{IntoResponses};

#[derive(Debug, Display, Error, IntoResponses)]
pub enum RouteError {
    /// No active tenant could be found for the provided tenant key
    #[response(status = FORBIDDEN)]
    TenantKeyNotFound,
    
    /// User agent header is required when user agent is not set in request JSON
    #[response(status = BAD_REQUEST)]
    MissingUserAgent,
}

And include it in the route like so:

#[utoipa::path(
    post,
    path = "/create",
    request_body = PostBody,
    params(QueryParams),
    responses(
        (status = 200, description = "Successfully created"),
        PostLogError,
        (status = 500, description = "Internal server error"),
    )
)]
pub async fn route() -> Result<StatusCode, RouteError> {}

But RouteError implements axum's IntoResponse trait which will transform the enum into a struct and sends that as the body instead of the enum variant itself:

use utoipa_gen::{ToSchema};

#[derive(Debug, Serialize, ToSchema)]
pub struct ErrorDto {
    pub status: u16,
    pub message: String,
}

Is it possible to let Utoipa know that this conversion is happening and include it as the response body in the OpenAPI schema?
