package archive/zip
NewReader returns a new Reader reading from r, which is assumed to have the given size in bytes.
zip.NewReader() function usage example
file, err := os.Open(“files.zip”)
if err != nil {
return err
}
defer file.Close()
const size = 8192 // fixed at 8KB, but in real life better to calculate size during runtime
var fileReader io.ReaderAt = file
if fileReader, err = zip.NewReader(file, size); err != nil {
return err
}
defer fileReader.Close()
