I propose something else: a DirEntry.inode read-only property (...)
Full DirEntry API:
- name (str) attribute
- path (str) read-only property, created at the first call
- inode (int or None) attribute <=== my proposition
- is_dir(*, follow_symlinks=True)
- is_file(*, follow_symlinks=True)
- is_symlink(*, follow_symlinks=True)
- stat(*, follow_symlinks=True)
is_dir(), is_file(), is_symlink() and stat() are method because they may all require a syscall (os.stat or os.lstat). They all cache their result. In some cases, the result is already known when DirEntry is created. In most cases, a single call to os.stat() is required to fill the result of all methods.
