golang-github-patrickmn-go-cache-dev binary package in Ubuntu Focal amd64

 go-cache is an in-memory key:value store/cache similar
 to memcached that is suitable for applications running on a single
 machine. Its major advantage is that, being essentially a thread-safe
 map[string]interface{} with expiration times, it doesn't need to serialize
 or transmit its contents over the network.
