Functions

func HexDecode

func HexDecode(input string) ([]byte, error)

Decode a hex string. Hex string can be optionally prefixed with 0x.

func HexEncode

func HexEncode(input []byte) string

Encode a bytearray as hex string with 0x prefix.

func IndexOf

func IndexOf(strs []string, str string) int

IndexOf returns the index of str in the slice; -1 if not found

func NormalizeString

func NormalizeString(str string) string

NormalizeString normalizes a string as NFKC

func RemoveDuplicatesFromUint64Slice

func RemoveDuplicatesFromUint64Slice(sliceList []uint64) []uint64

func StrNotSet

func StrNotSet(value string) bool

StrNotSet will return true if the string value provided is empty

func ToNumeric

func ToNumeric(i *big.Int) decimal.Decimal

func ValidateString

func ValidateString(str string, forbidden ...string) error

ValidateString checks if the given string is:

1. non-empty 2. entirely composed of utf8 runes 3. normalized as NFKC 4. does not contain any forbidden Unicode code points

func ValidateStringAllowEmpty

func ValidateStringAllowEmpty(str string, forbidden string) error

ValidateStringAllowEmpty checks if the given string is:

1. entirely composed of utf8 runes 2. normalized as NFKC 3. does not contain any forbidden Unicode code points

Types

type Nonce

type Nonce [sha256.Size]byte

Nonce defines a 32 byte array representing a deterministically-generated nonce

func GetNonce

func GetNonce(hash tmbytes.HexBytes, gasMeter sdk.GasMeter) Nonce

GetNonce deterministically calculates a nonce using a hash and gas meter

type Threshold

type Threshold struct {
	// split threshold into Numerator and denominator to avoid floating point
	// errors down the line
	Numerator   int64 `protobuf:"varint,1,opt,name=numerator,proto3" json:"numerator,omitempty"`
	Denominator int64 `protobuf:"varint,2,opt,name=denominator,proto3" json:"denominator,omitempty"`
}
