You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: zip_test.go
    path of file: ./repos/compress/zstd
    
    the code of the file until where you have to start completion: package zstd_test

	"archive/zip"
	"bytes"
	"fmt"
	"io"

	"github.com/klauspost/compress/zstd"

	// These can be used by multiple readers and writers.

	// Try it out...
