Struct CacheControlService

pub struct CacheControlService<S>
where
    S: Clone + Send + Sync + 'static,
{ /* private fields */ }

Cache-Control setter Service.

Assigns a value based on a response status:

• on 1xx and 2xx takes a no-cache request header directive or falls back to a default one;
• on 301, likely a permanent move, sets a day TTL and asks CDN to cache the response, too;
• on any other 3xx takes the default and prevents CDN from caching the response;
• on 4xx caching is disabled;
• on 5xx 30 min TTL is set.

TTL defaults to 5 seconds.

Trait Implementations

impl<S> Clone for CacheControlService<S>

where S: Clone + Send + Sync + 'static + Clone,

fn clone(&self) -> CacheControlService<S>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S> Debug for CacheControlService<S>

where S: Clone + Send + Sync + 'static + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<ReqB, ResB, S> Service<Request<ReqB>> for CacheControlService<S>

where S: Service<Request<ReqB>, Response = Response<ResB>> + Clone + Send + Sync + 'static, S::Future: Send + 'static, ReqB: Send + 'static, ResB: Send + 'static,

type Response = <S as Service<Request<ReqB>>>::Response

Responses given by the service.

type Error = <S as Service<Request<ReqB>>>::Error

Errors produced by the service.

type Future = Pin<Box<dyn Future<Output = Result<<CacheControlService<S> as Service<Request<ReqB>>>::Response, <CacheControlService<S> as Service<Request<ReqB>>>::Error>> + Send>>

The future response value.

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, req: Request<ReqB>) -> Self::Future
