This change updates the cfg attribute to prevent unnecessary file metadata fetching on a new target.
The current
DirEntry::file_type
implementation returns a pre-parsed value fromfs::read_dir
for most targets. Some Unix operating systems are excluded because of the overhead of fetching metadata to get the file type. However, as the Rust compiler has been updated, a new target has been added and an update is needed. The cfg attribute is taken from the std implementation.Related Issue: #5806
