Struct Cache

Source 
pub struct Cache<S> { /* private fields */ }
Expand description

Implement a HTTP cache.

Implementations§

Source§

impl<S> Cache<S>
where S: CacheStorage,

Source

pub fn new(storage: S) -> Self

Construct a new cache with the given storage.

Defaults to a private cache.

Source

pub fn new_with_options(storage: S, options: CacheOptions) -> Self

Construct a new cache with the given storage and options.

Source

pub fn storage(&self) -> &S

Gets the storage used by the cache.

Source

pub async fn send<B: HttpBody>( &self, request: impl Request<B>, ) -> Result<Response<Body<B>>>

Sends a HTTP request through the cache.

If a previous response is cached and not stale, the request is not sent upstream and the cached response is returned.

If a previous response is cached and is stale, the response is revalidated, the cache is updated, and the cached response returned.

If a previous response is not in the cache, the request is sent upstream and the response is cached, if it is cacheable.
