If you store a reference type like a pointer, slice, map or channel, you do not need to
run Set if you modify the underlying data. The cache does not serialize its data, so if
you modify a struct whose pointer you've stored in the cache, retrieving that pointer
with Get will point you to the same data:

Reference:
func New(de, ci time.Duration) *Cache
Returns a new cache with a given default expiration duration and default cleanup
interval. If the expiration duration is less than 1, the items in the cache never
expire and must be deleted manually. If the cleanup interval is less than one,
expired items are not deleted from the cache before their next lookup or before
calling DeleteExpired.
func New(de, ci time.Duration) *Cache
Returns a new cache with a given default expiration duration and default cleanup
interval. If the expiration duration is less than 1, the items in the cache never
expire and must be deleted manually. If the cleanup interval is less than one,
expired items are not deleted from the cache before their next lookup or before
calling DeleteExpired.
func (c *Cache) Set(k string, x interface{}, d time.Duration)
Adds an item to the cache, replacing any existing item. If the duration is 0, the
cache's default expiration time is used. If it is -1, the item never expires.
func (c *Cache) Set(k string, x interface{}, d time.Duration)
Adds an item to the cache, replacing any existing item. If the duration is 0, the
cache's default expiration time is used. If it is -1, the item never expires.
func (c *Cache) Add(k string, x interface{}, d time.Duration) error
Adds an item to the cache only if an item doesn't already exist for the given key,
or if the existing item has expired. Returns an error if not.
func (c *Cache) Add(k string, x interface{}, d time.Duration) error
Adds an item to the cache only if an item doesn't already exist for the given key,
or if the existing item has expired. Returns an error if not.
func (c *Cache) Replace(k string, x interface{}, d time.Duration) error
Sets a new value for the cache item only if it already exists. Returns an error if
it does not.
func (c *Cache) Replace(k string, x interface{}, d time.Duration) error
Sets a new value for the cache item only if it already exists. Returns an error if
it does not.
func (c *Cache) Get(k string) (interface{}, bool)
Gets an item from the cache. Returns the item or nil, and a bool indicating whether
the given key was found in the cache.
func (c *Cache) Get(k string) (interface{}, bool)
Gets an item from the cache. Returns the item or nil, and a bool indicating whether
the given key was found in the cache.
func (c *Cache) Increment(k string, n int64) error
Increment an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, or uint64, float32 or float64 by n. Returns an error if the item's value
is not an integer, if it was not found, or if it is not possible to increment it
by n. Passing a negative number will cause the item to be decremented.
func (c *Cache) Increment(k string, n int64) error
Increment an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, or uint64, float32 or float64 by n. Returns an error if the item's value
is not an integer, if it was not found, or if it is not possible to increment it
by n. Passing a negative number will cause the item to be decremented.
func (c *Cache) IncrementFloat(k string, n float64) error
Increment an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, uint64, float32 or float64 by n. Returns an error if the item's value is
not an integer, if it was not found, or if it is not possible to increment it by
n. Passing a negative number will cause the item to be decremented.
func (c *Cache) IncrementFloat(k string, n float64) error
Increment an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, uint64, float32 or float64 by n. Returns an error if the item's value is
not an integer, if it was not found, or if it is not possible to increment it by
n. Passing a negative number will cause the item to be decremented.
func (c *Cache) Decrement(k string, n int64) error
Decrement an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, or uint64, float32 or float64 by n. Returns an error if the item's value
is not an integer, if it was not found, or if it is not possible to decrement it
by n.
func (c *Cache) Decrement(k string, n int64) error
Decrement an item of type int, int8, int16, int32, int64, uintptr, uint, uint8,
uint32, or uint64, float32 or float64 by n. Returns an error if the item's value
is not an integer, if it was not found, or if it is not possible to decrement it
by n.
func (c *Cache) Delete(k string)
Deletes an item from the cache. Does nothing if the item does not exist in the cache.
func (c *Cache) Delete(k string)
Deletes an item from the cache. Does nothing if the item does not exist in the cache.
func (c *Cache) DeleteExpired()
Deletes all expired items from the cache.
func (c *Cache) DeleteExpired()
Deletes all expired items from the cache.
func (c *Cache) Flush()
Deletes all items from the cache.
func (c *Cache) Flush()
Deletes all items from the cache.
