Variables ¶
var ( // MaxSafeJSInt represents max value which JS support // It is used for smartContract fields // Our staking repo is written in JS, as are many other clients // If we use higher value JS will not be able to parse it MaxSafeJSInt = uint64(math.Pow(2, 53) - 2) )
Functions ¶
func BigIntDivCeil ¶
BigIntDivCeil performs integer division and rounds given result to next bigger integer number It is calculated using this formula result = (a + b - 1) / b
func ConvertUnmarshalledUint ¶
func CreateDirSafe ¶
Creates a directory at path and with perms level permissions. If directory already exists, owner and permissions are verified.
func DirectoryExists ¶
DirectoryExists checks if the directory at the specified path exists
func EncodeBytesToUint64 ¶
EncodeBytesToUint64 big endian byte slice to uint64
func EncodeUint64ToBytes ¶
EncodeUint64ToBytes encodes provided uint64 to big endian byte slice
func ExtendByteSlice ¶
ExtendByteSlice extends given byte slice by needLength parameter and trims it
func FileExists ¶
Checks if the file at the specified path exists
func GetTerminationSignalCh ¶
GetTerminationSignalCh returns a channel to emit signals by ctrl + c
func PadLeftOrTrim ¶
PadLeftOrTrim left-pads the passed in byte array to the specified size, or trims the array if it exceeds the passed in size
func SaveFileSafe ¶
Creates a file at path and with perms level permissions. If file already exists, owner and permissions are verified, and the file is overwritten.
func SetupDataDir ¶
SetupDataDir sets up the data directory and the corresponding sub-directories
func ToFixedFloat ¶
Types ¶
type JSONNumber ¶
type JSONNumber struct {
Value uint64
}
JSONNumber is the number represented in decimal or hex in json
func (*JSONNumber) MarshalJSON ¶
func (d *JSONNumber) MarshalJSON() ([]byte, error)
func (*JSONNumber) UnmarshalJSON ¶
func (d *JSONNumber) UnmarshalJSON(data []byte) error
