// This code is taken from https://github.com/golang/go/blob/go1.17/src/io/fs/readdir.go#L49-L77
|
||
|
|
// and provides the io/fs.FileInfoToDirEntry() utility for go1.16. Go 1.16 and up
|
||
|
|
// provide a new implementation of ioutil.ReadDir() (in os.ReadDir()) that returns
|
||
|
|
// an os.DirEntry instead of fs.FileInfo. go1.17 added the io/fs.FileInfoToDirEntry()
|
||
|
|
// utility to allow existing uses of ReadDir() to get the old type. This utility
|
||
|
|
// is not available in go1.16, so we copied it to assist the migration to os.ReadDir().
