Exists checks if specified file, directory, or symlink exists.

ReadDirNoStat returns a string of files/directories contained in dirname without calling lstat on them.

CheckFollowSymlink follows the symlink and verifies that the target of the symlink exists.

CheckSymlinkOnly does not follow the symlink and verifies only that they symlink itself exists.

ErrInvalidLinkTreatment indicates that the link treatment behavior requested is not a valid behavior.

LinkTreatment is the base type for constants used by Exists that indicate how symlinks are treated for existence checks.
