Trait ResponseFilter 

pub trait ResponseFilter: Send + Sync {
    // Required method
    fn filter(&self, request: &mut ResponseContext<'_>) -> TiiResult<()>;
}

Trait for a filter that may alter a Response after an endpoint has been called or a filter has aborted the request. Use cases: (Non-Exhaustive)

• Adding Cors headers
• Adding Various other headers
• Logging of the response
• “Rough” estimation of the time it takes for the endpoint to process things.

Required Methods

fn filter(&self, request: &mut ResponseContext<'_>) -> TiiResult<()>

Called with the request context adn response after the endpoint or error handler is called. Ok(…) -> proceed. Err -> Call error handler and proceed. (You cannot create a loop, a Response filter will only be called exactly once per RequestContext)
