type BufferedWriter struct {
	N int
	// contains filtered or unexported fields
}

BufferedWriter buffers the last N bytes written to it.

It does not error if more writes happen but uses a circular buffer and keeps only the last N bytes.

Use Bytes() to access the buffer.

func (b *BufferedWriter) Bytes() []byte

func (b *BufferedWriter) Write(p []byte) (int, error)

type Error struct {
	Err error
}

Error is a io.ReadWriteClose implementation that returns the underlying error for everything.

func (e Error) Close() error

func (e Error) Read(p []byte) (int, error)

func (e Error) Write(p []byte) (int, error)

type LimitedWriter struct {
	N int
	// contains filtered or unexported fields
}

LimitedWriter limits write to a max of specified number of bytes.

It returns ErrLimitExceeded if the write exceeds this limit.

func (l *LimitedWriter) Bytes() []byte

func (l *LimitedWriter) Write(p []byte) (int, error)

type ReadCloser struct {
	io.Reader
	io.Closer
}

type WriteCloser struct {
	io.Writer
	io.Closer
}

WriteCloser provides a simple way to create an io.WriteCloser by combining io.Writer and io.Closer
