Functions

func JoinBytes

func JoinBytes(bytes ...interface{}) []byte

JoinBytes is an easy way to join multiple values into a single []byte

func SysFreeMemory

func SysFreeMemory() float64

SysFreeMemory returns the amount of memory available in megabytes

func ToNumber

func ToNumber[T interface {
	int | int8 | int16 | int32 | int64 | uint | uint8 | uint16 | uint32 | uint64 | uintptr | float64 | float32
}](val interface{}) T

toNumber converts multiple types to a number

accepts: int (and variants), string, []byte, byte, bool

func ToString

func ToString[T interface{ string | []byte }](val interface{}) T

toString converts multiple types to a string|[]byte

accepts: string, []byte, byte, int (and variants), [][]byte, []interface{}

Types

type CacheMap

type CacheMap[T any] struct {
	// contains filtered or unexported fields
}

func NewCache

func NewCache[T any]() CacheMap[T]

func (*CacheMap[T]) DelOld

func (cache *CacheMap[T]) DelOld(cacheTime time.Duration)

delOld removes old cache items

func (*CacheMap[T]) Get

func (cache *CacheMap[T]) Get(key string) (T, error)

get returns a value or an error if it exists

if the object key does not exist, it will return both a nil/zero value (of the relevant type) and nil error

func (*CacheMap[T]) Set

func (cache *CacheMap[T]) Set(key string, value T, err error)

set sets or adds a new key with either a value, or an error
