Struct Cache 

pub struct Cache<S>(/* private fields */);

Implements a caching middleware for reqwest.

Implementations

impl<S: CacheStorage> Cache<S>

pub fn new(storage: S) -> Self

Constructs a new caching middleware with the given storage.

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

Construct a new caching middleware with the given storage and options.

pub fn with_revalidation_hook( self, hook: impl Fn(&dyn RequestLike, &mut HeaderMap) -> Result<()> + Send + Sync + 'static, ) -> Self

Sets the revalidation hook to use.

The hook is provided the original request and a mutable header map containing headers explicitly set for the revalidation request.

For example, a hook may alter the revalidation headers to update an Authorization header based on the headers used for revalidation.

If the hook returns an error, the error is propagated out as the result of the original request.

pub fn storage(&self) -> &S

Gets the underlying storage of the cache.

Trait Implementations

impl<S: CacheStorage> Middleware for Cache<S>

fn handle<'a, 'b, 'c, 'd>( &'a self, req: Request, extensions: &'b mut Extensions, next: Next<'c>, ) -> BoxFuture<'d, Result<Response>>

where Self: 'd, 'a: 'd, 'b: 'd, 'c: 'd,

Invoked with a request before sending it. If you want to continue processing the request, you should explicitly call next.run(req, extensions).
