Overview

We will refactor it later! But we support now sdk.Int as u128 for Libra u128. It's allows us to use balances from cosmos!

Functions

func BigToBytes

func BigToBytes(val sdk.Int, bytesLen int) []byte

Convert sdk.Int to bytes with little endian (required by Libra).

func IsEthereumAddress

func IsEthereumAddress(address string) bool

Check if it's ethereum address.

func LeToBig

func LeToBig(bytes []byte) sdk.Int

Convert little endian bytes to big endian bytes and then to sdk.Int.

func Marshal

func Marshal(v interface{}) ([]byte, error)

func Unmarshal

func Unmarshal(data []byte, v interface{}) error

Types

type Decoder

type Decoder struct {
	// contains filtered or unexported fields
}

func NewDecoder

func NewDecoder(r io.Reader) *Decoder

func (*Decoder) Decode

func (d *Decoder) Decode(v interface{}) error

func (*Decoder) EOF

func (d *Decoder) EOF() bool

type Encoder

type Encoder struct {
	// contains filtered or unexported fields
}

func NewEncoder

func NewEncoder(w io.Writer) *Encoder

func (*Encoder) Encode

func (e *Encoder) Encode(v interface{}) error

type EnumTypeUser

type EnumTypeUser interface {
	// EnumTypes return the ingredients used for all enum types in the struct.
	EnumTypes() []EnumVariant
}

EnumTypeUser is an interface of struct with enum type definition. Struct with enum type should implement this interface.

type EnumVariant

type EnumVariant struct {
	// Name of the enum type. Different variants of a same enum type should have same name.
	// This name should match the name defined in the struct field tag.
	Name string

	// Value is the numeric value of the enum variant. Should be unique within the same enum type.
	Value int32

	// Template object for the enum variant. Should be the zero value of the variant type.
	//
	// Example values: (*SomeStruct)(nil), MyUint32(0).
	Template interface{}
}

EnumVariant is a definition of a variant of enum type.
