vjson

JSON wrapper for use in Vugu

The purpose of this package is to provide Marshal and Unmarshal methods that work on built-in types and builds and runs correctly under regular Go and in Tinygo (as of v0.9.0 Tinygo does not support encoding/json)

Documentation

Overview

Package vjson is a small, minimal alternative to encoding/json which has no dependencies and works with Tingyo. The Marshal and Unmarshal methods work like encoding/json, but structs are not supported, only primitives plus map[string]interface{} and []interface{}.

Functions

func Marshal

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

func Unmarshal

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

Types

type Delim

type Delim rune

A Delim is a JSON array or object delimiter, one of [ ] { or }.

func (Delim) String

func (d Delim) String() string

type Marshaler

type Marshaler interface {
	MarshalJSON() ([]byte, error)
}

Marshaler is the interface implemented by types that can marshal themselves into valid JSON.

type Number

type Number string

A Number represents a JSON number literal.

func (Number) Float64

func (n Number) Float64() (float64, error)

Float64 returns the number as a float64.

func (Number) Int64

func (n Number) Int64() (int64, error)

Int64 returns the number as an int64.

func (Number) String

func (n Number) String() string

String returns the literal text of the number.

type RawMessage

type RawMessage []byte

RawMessage is a raw encoded JSON value. It implements Marshaler and Unmarshaler and can be used to delay JSON decoding or precompute a JSON encoding.

func (RawMessage) MarshalJSON

func (m RawMessage) MarshalJSON() ([]byte, error)

MarshalJSON returns m as the JSON encoding of m.

func (*RawMessage) UnmarshalJSON

func (m *RawMessage) UnmarshalJSON(data []byte) error

UnmarshalJSON sets *m to a copy of data.

type Token

type Token interface{}

A Token holds a value of one of these types:

Delim, for the four JSON delimiters [ ] { }
bool, for JSON booleans
float64, for JSON numbers
Number, for JSON numbers
string, for JSON string literals
nil, for JSON null

type Unmarshaler

type Unmarshaler interface {
	UnmarshalJSON([]byte) error
}

Unmarshaler is the interface implemented by types that can unmarshal a JSON description of themselves.
