->Simple clj/s

(->Simple impl)

(->Simple impl miss)

Converts a CacheProtocol into a SimpleCache. The miss function will be invoked with the entry to determine and set the value if not found. Implements IFn as an alternative to invoking SimpleCache/get

WARNING: CLJS has a IFn argument limit of 20 args for both Apply and Invoke

->Simple-Fn-Cache clj/s

(->Simple-Fn-Cache {:keys [key-fn cache-fn miss-fn evict-fn reset-fn]
                    :or {key-fn identity}})

Constructs a function-backed SimpleCache. The miss function will be invoked with the entry to determine and set the value if not found. Implements IFn as an alternative to invoking SimpleCache/get
