decrement(name, amount = 1, options = nil) public Decrement a cached integer value using the memcached decr atomic operator. Returns the updated value.
If the key is unset or has expired, it will be set to 0. Memcached does not support negative counters.
cache.decrement("foo") # => 0
To set a specific value, call #write passing raw: true:
cache.write("baz", 5, raw: true) cache.decrement("baz") # => 4
Decrementing a non-numeric value, or a value written without raw: true, will fail and return nil.
