Documentation for cache

I can't seem to find any vapor 4 documentation for cache. Is it deprecated?
No it's not deprecated.
See https://github.com/vapor/vapor/releases?q=cache&expanded=true
Configure application cache
app.caches.use(.memory)
Set cached value
app.cache.set("foo", to: "mads")
app.cache.set("foo", to: "mads", expiresIn: .seconds(30))
Get value from cache
app.cache.get("foo", as: String.self)
Use in request handler
req.cache.get("foo", as: String.self)
(Includes .memory cache which stores values in a thread-safe dictionary)
Thank you! Any notes on the time complexity? Is this just a wrapper around NSCache?
@henrypratt Sorry, I have no idea about the internals, I didn’t look closely at the code.
@henrypratt You might be interested in a cache with a fixed capacity and an LRU algorithm:

No, NSCache is not involved (if it's even implemented by swift-corelibs-foundation, I don't know...)
Vapor's MemoryCache is implemented from scratch here: MemoryCache.swift.
