Types

type Reader

type Reader interface {
	// Read reads the given bytes and returns the number of bytes read.
	Read([]byte) (int, error)

	// SHA256Hash returns the SHA256 hash of what's read.
	SHA256Hash() hash.Hash

	// N is a record of the total number of bytes read so far.
	N() int64
}

Reader describes a reader with a record of the number of bytes and a sha256 hash of what's read.

func NewReader

func NewReader(r io.Reader) Reader

NewReader creates a new Reader

type ReaderWithContext

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

ReaderWithContext provides an implementation of Reader.

func (*ReaderWithContext) N

func (r *ReaderWithContext) N() int64

N returns the total number of bytes read.

func (*ReaderWithContext) Read

func (r *ReaderWithContext) Read(p []byte) (int, error)

Read reads the given bytes

func (*ReaderWithContext) SHA256Hash

func (r *ReaderWithContext) SHA256Hash() hash.Hash

SHA256Hash returns the SHA256 hash of the bytes read.
