Struct Writer

internal/snapref/encode.go:148–164

Writer is an io.Writer that can write Snappy-compressed bytes. Writer handles the Snappy stream format, not the Snappy block format.

//

	w   io.Writer
	err error

	// ibuf is a buffer for the incoming (uncompressed) bytes.
	//
	// Its use is optional. For backwards compatibility, Writers created by the
	// NewWriter function have ibuf == nil, do not buffer incoming bytes, and
	// therefore do not need to be Flush'ed or Close'd.
	ibuf []byte

	// obuf is a buffer for the outgoing (compressed) bytes.
	obuf []byte

	// wroteStreamHeader is whether we have written the stream header.
	wroteStreamHeader bool
}

// Reset discards the writer's state and switches the Snappy writer to write to
// w. This permits reusing a Writer rather than allocating a new one.
