§Example Usage

#[derive(axum_enum_response::EnumIntoResponse)]
enum ErrorResponse {
   #[status_code(UNAUTHORIZED)]
   Unauthorized, // 401, empty body
   #[status_code(OK)]
   #[body("hello"=>"world")]
   Ok, // 200, body = {"hello": "world"}
   #[status_code(FORBIDDEN)]
   #[body("mew")]
   Forbidden, // 403, body = {"error": "mew"}
   #[status_code(INTERNAL_SERVER_ERROR)]
   FromUtf8Error(#[from] FromUtf8Error), // 500, body = {"error": FromUtf8Error::to_string()}
   #[status_code(INTERNAL_SERVER_ERROR)]
   InternalServerError(#[key("awwa")] String), // 500, body = {"awwa": STRING}
}

You can also use any struct that implements serde::Serialize as a field like this:

#[derive(serde::Serialize)]
struct SomeData {
    meow: String,
}

#[derive(axum_enum_response::EnumIntoResponse)]
enum ErrorResponse {
    #[status_code(BAD_REQUEST)]
    BadRequest(SomeData), // 400, body = {"meow": STRING}
}
