Struct Listing 

struct Listing<'a> {
    store: &'a str,
    root: &'a Path,
    skip: &'a [&'a str],
    known: &'a BTreeMap<String, Stat>,
    confirmed: bool,
    files: &'a mut Vec<(String, PathBuf)>,
    found: &'a mut Found,
}

A listing of a folder of files sealed apart (notes, papers).

Fields

store: &'a str

root: &'a Path

skip: &'a [&'a str]

known: &'a BTreeMap<String, Stat>

confirmed: bool

You said to take out what went from it: a folder listing empty is emptied.

files: &'a mut Vec<(String, PathBuf)>

found: &'a mut Found

Implementations

impl Listing<'_>

fn list(&mut self, dir: &Path) -> usize

Every file below dir, by its path from the root with /; how many. Left out: what sync apps, editors and systems make (made_by_tools), skip at the top (whatever its case), tools’ own folders, a folder shared through (it holds a seal), links, names that are not text (said). A folder that cannot be read whole (one name that errs is enough), or that lists empty while it held files at the last look (a disk not mounted, access withdrawn), is unknown: nothing in it is taken out elsewhere, nothing is written into it.
