Rails.cache.fetch ('nil thing') { nil }

Cache read: nil thing
Cache generate: nil thing
Cache write: nil thing

Rails.cache.fetch ('nil thing') { nil }

Note: it can't find it, so it regenerates it.

Cache read: nil thing
Cache generate: nil thing
Cache write: nil thing

Rails.cache.fetch ('one thing') { 1 }

Cache read: one thing
Cache generate: one thing
Cache write: one thing

Rails.cache.fetch ('one thing') { 1 }

Note: it can find it, so there's a cache fetch_hit.

Cache read: one thing
Cache fetch_hit: one thing
