This function returns an error if the bytes represent JSON that is malformed or does not conform to the JSON Cadence specification.

func Encode(value cadence.Value) ([]byte, error)

Encode returns the JSON-encoded representation of the given value.

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

A Decoder decodes JSON-encoded representations of Cadence values.

func NewDecoder(r io.Reader) *Decoder

NewDecoder initializes a Decoder that will decode JSON-encoded bytes from the given io.Reader.

func (d *Decoder) Decode() (value cadence.Value, err error)

Decode reads JSON-encoded bytes from the io.Reader and decodes them to a Cadence value.

This function returns an error if the bytes represent JSON that is malformed or does not conform to the JSON Cadence specification.

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

An Encoder converts Cadence values into JSON-encoded bytes.

func NewEncoder(w io.Writer) *Encoder

NewEncoder initializes an Encoder that will write JSON-encoded bytes to the given io.Writer.

func (e *Encoder) Encode(value cadence.Value) (err error)

Encode writes the JSON-encoded representation of the given value to this encoder's io.Writer.

This function returns an error if the given value's type is not supported by this encoder.
