Struct ProblemDetails 

pub struct ProblemDetails {
    pub problem_type: String,
    pub title: String,
    pub status: u16,
    pub detail: Option<String>,
    pub instance: Option<String>,
}

RFC 9457 Problem Details response.

Wire format:

{
  "type": "about:blank",
  "title": "Bad Request",
  "status": 400,
  "detail": "api_key cannot be empty"
}
