Types ¶
type Cache ¶
type Cache interface {
// Save preserve provided value under given key.
Save(key string, value interface{})
// GetSaved retrieve value from given key.
GetSaved(key string) (interface{}, error)
// Reset turns cache into init state - clears all entries.
Reset()
// All returns all cache entries.
All() map[string]interface{}
}
Cache is entity that has ability to store/retrieve arbitrary values.
type ConcurrentCache ¶ added in v0.8.5
type ConcurrentCache struct {
// contains filtered or unexported fields
}
ConcurrentCache is entity that has ability to store and retrieve arbitrary values. Safe for concurrent use.
func NewConcurrentCache ¶ added in v0.8.5
func NewConcurrentCache() *ConcurrentCache
NewConcurrentCache returns pointer to ConcurrentCache safe for concurrent use

All returns all current cache data.
func (*DefaultCache) GetSaved ¶
func (c *DefaultCache) GetSaved(key string) (interface{}, error)
GetSaved returns preserved value if present, error otherwise.
func (*DefaultCache) Reset ¶
