type Cache ¶
type Cache interface {
Add(key []byte, value interface{}) error
Get(key []byte) (value interface{}, ok bool)
Set(key []byte, value interface{}) error
SetWithExpiration(key []byte, value interface{}, expiration time.Duration) error

}
Cache is an anstract cache layer
type Fixed64 ¶
type Fixed64 int64
the 64 bit fixed-point number, precise 10^-8
func StringToFixed64 ¶
type GoCache ¶
GoCache is the caching layer implemented by go-cache.
func NewGoCache ¶
NewGoCache creates a go-cache cache with a given default expiration duration and cleanup interval.
func (*GoCache) Add ¶
Add 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 otherwise.
func (*GoCache) Delete ¶
Delete deletes an item from the cache. Does nothing if the key is not in the cache.
func (*GoCache) Get ¶
Get gets an item from the cache. Returns the item or nil, and a bool indicating whether the key was found.

type Uint160 [UINT160SIZE]uint8
var EmptyUint160 Uint160
func BigToUint160 ¶
