func CalcFileSHA256Bytes ¶
CalcFileSHA256 is used to calculate the sha256 value of the file type.
func CalcPathSHA256 ¶
CalcPathSHA256 is used to calculate the sha256 value of a file with a given path.
func CalcPathSHA256Bytes ¶
CalcPathSHA256 is used to calculate the sha256 value of a file with a given path.
func CalcSHA256 ¶

func CheckBucketName ¶
func CheckDomain ¶
CheckDomain returns an error if the domain name is not valid. See https://tools.ietf.org/html/rfc1034#section-3.5 and https://tools.ietf.org/html/rfc1123#section-2.
func CompareSlice ¶
func DateTimeToUnix ¶ added in v0.4.28
func GenerateFile ¶ added in v0.5.1
func GetDirFreeSpace ¶
func GetSysMemAvailable ¶
func GetUnixTimeAtZeroToday ¶ added in v0.4.28
func GetUnixTimeAtZeroToday() int64
func IsInterfaceNIL ¶ added in v0.4.32
func IsInterfaceNIL(i interface{}) bool
func IsIntranetIpv4 ¶ added in v0.4.32
func IsPortInUse ¶ added in v0.4.32
func IsWorkerPublicKeyAllZero ¶ added in v0.4.32
func IsWorkerPublicKeyAllZero(puk pattern.WorkerPublicKey) bool
func NumsToByteStr ¶
NumsToByteStr utility function takes an array of unsigned integers and output the corresponding byte string representing it. For example: `[18, 15]` to `120F`.
For `opts` in second parameter it is a map expecting:
- `space` bool: whether to add a space between each byte, default to `false`
- `prefix` bool: whether to add `0x` as the prefix, default to `false`
- `uppercase` bool: whether to display hexadecimal in upper case, default to `true`
If there is an integer larger than 255 in the array, an error is returned.
func NumsToByteStrDefault ¶
func NumsToByteStrDefault[T constraints.Unsigned](nums []T) (string, error)
func ParsingPublickey ¶
func PingNode ¶ added in v0.5.1
PingNode be used to ping target node by ICMP protocol, It returns the TTL from target node. Requires root privileges to use.
func RecoverError ¶
func RecoverError(err interface{}) error
RecoverError is used to record the stack information of panic
func TraceRoute ¶ added in v0.5.1
TraceRoute be used to trace route to target node by ICMP protocol, It returns the distance and TTL from target node. Requires root privileges to use
func VerityAddress ¶
func WriteBufToFile ¶
