Types

type Item

type Item struct {
	Key         string        // key of the item
	Value       any           // Value of the item
	Expiration  time.Duration // Expiration duration of the item
	LastAccess  time.Time     // LastAccess time of the item
	AccessCount uint          // AccessCount of times the item has been accessed
}

Item is a struct that represents an item in the cache. It has a key, value, expiration duration, and a last access time field.

func (*Item) Expired

func (item *Item) Expired() bool

Expired returns true if the item has expired, false otherwise.

func (*Item) FieldByName

func (item *Item) FieldByName(name string) reflect.Value

FieldByName returns the value of the field of the Item struct with the given name. If the field does not exist, an empty reflect.Value is returned.

func (*Item) MarshalBinary

func (item *Item) MarshalBinary() (data []byte, err error)

UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.

func (item *Item) UnmarshalBinary(data []byte) error {
	buf := bytes.NewBuffer(data)
	dec := gob.NewDecoder(buf)
	return dec.Decode(item)
}

MarshalBinary implements the encoding.BinaryMarshaler interface.

func (*Item) Touch

func (item *Item) Touch()

Touch updates the last access time of the item and increments the access count.

func (*Item) UnmarshalBinary

func (item *Item) UnmarshalBinary(data []byte) error

UnmarshalBinary implements the encoding.BinaryUnmarshaler interface.

func (*Item) Valid

func (item *Item) Valid() error

Valid returns an error if the item is invalid, nil otherwise.
