Function foreman::rerun_walk

pub fn rerun_walk<CB: FnMut(&Path) -> bool>(p: &Path, callback: CB)

Recursively walk a directory, calling the provided callback for each file and directory, and if it returns true, tell cargo to trigger a rerun of the build script. Hidden files are included, but errors are ignored (so directories that you do not have permission to access will be silently skipped).
