http-cache

A caching middleware that follows HTTP caching rules, thanks to http-cache-semantics. By default it uses cacache as the backend cache manager.

Supported Clients

• Surf *Should likely be registered after any middleware modifying the request
• Reqwest *Uses reqwest-middleware for middleware support

Install

With cargo add installed :

cargo add http-cache
