Process A Directory Recursitvely In Rust
This is a stright copy from The Rust Cookbookrcb. It hits all files that aren't hidden (i.e. that don't start with a .)
use walkdir::{DirEntry, WalkDir};
fn is_not_hidden(entry: &DirEntry) -> bool {
entry
.file_name()
.to_str()
.map(|s| entry.depth() == 0 || !s.starts_with("."))
.unwrap_or(false)
}
fn main() {
WalkDir::new(".")
.into_iter()
.filter_entry(|e| is_not_hidden(e))
.filter_map(|v| v.ok())
.for_each(|x| println!("{}", x.path().display()));
