Module fstree 

Filesystem scanner that transforms a directory into source-neutral tree data, lazily: scan walks only the top level, and each directory’s contents come from a targeted depth-1 walk when it is expanded or when the app’s background sweep reaches it. The targeted walk keeps full ignore semantics — ignore::WalkBuilder’s standard filters read ignore files in parent directories, so a lazily walked subdirectory honors the same rules the eager scan did. Unreadable directories are reported through the tree’s error list (banner + stderr on exit) instead of being skipped silently.

Functions

scan

Scan dir’s top level, honoring ignore files unless no_ignore is set.
