Module fs 

Filesystem helpers shared by the ecosystem crawlers.

Each crawler walks one or more package directories and decides whether each entry is a candidate package. The two operations that all eight crawlers repeat are:

• listing entries in a directory while tolerating permission / I/O errors (we treat an unreadable directory as “no entries”);
• asking whether an entry is a directory while tolerating file_type() failures (we treat a stat error as “not a dir”).

Centralizing both keeps each crawler free of the match read_dir { Ok(rd) => rd, Err(_) => return … } boilerplate and gives integration tests a single function to drive when they want to exercise the read_dir Err arm via chmod 000.

Both helpers are async because the rest of the crawler code is — they delegate to tokio::fs.

Symlinks

entry_is_dir follows symlinks (uses metadata(), not symlink_metadata()), matching the historical behavior of the crawlers (pnpm’s content-addressed store relies on resolving symlinks into node_modules/.pnpm/*).

Functions

entry_file_type

Return the raw FileType for entry, swallowing stat errors.

entry_is_dir

Resolve whether entry is a directory, following symlinks.

list_dir_entries

List the immediate children of path.
