Functions

func Unmarshal

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

Unmarshal is a mirror of json.Unmarshal, for RIFF files

Types

type INFO struct {
	// Arhcival Location
	IARL string `riff:"IARL"`
	// Arist

}

INFO is a common RIFF component. Most of these fields will be absent on any given INFO struct. Todo: consider if these should be given names that are informative instead of representative of their structural tag

type Reader

type Reader struct {
	*bytes.Reader
}

A Reader is a bytes reader with some helper functions to read IDs, Lens, and Data from RIFF files.

func NewReader

func NewReader(data []byte) *Reader

NewReader returns an initial Reader

func (*Reader) NextID

func (r *Reader) NextID() (string, error)

NextID returns the next four byte sof the reader as a string

func (*Reader) NextIDLen

func (r *Reader) NextIDLen() (string, uint32, bool, error)

NextIDLen returns NextID and NextLen

func (*Reader) NextLen

func (r *Reader) NextLen() (uint32, error)

NextLen returns the next four bytes of the reader as a length.

func (*Reader) Print

func (r *Reader) Print()

Print prints a reader without any knowledge of the structure of the reader, so all values will be []bytes. It assumes the reader has not advanced at all. Todo: Change that
