-//! ref: composer/vendor/symfony/finder/Finder.php
-//!
-//! The iterator pipeline of `searchInDirectory()` is reproduced inline here
-//! instead of as separate `Iterator\*` classes. Entries are materialized as
-//! `PathBuf` (the SplFileInfo replacement); the relative-path information that
-//! `RecursiveDirectoryIterator` attaches to each `SplFileInfo` is carried on the
-//! private `Entry` struct so the path/exclude filters keep their exact behavior.
