Enum Tier 

pub enum Tier {
    Named,
    Ignored,
}

Which tier claimed a directory.

The asymmetry is information rather than an accident of implementation: a named row is a directory whose cost to lose is known, and an unnamed one is a leap. That is worth being able to filter on in both directions.

Variants

Named

A rule named it, so it carries an ecosystem and a Kind.

Ignored

Only the gitignore fallback found it. Nothing knows what it is.

Implementations

impl Tier

pub fn of(hit: &Hit) -> Option<Self>

Which member of the tier axis judges this hit, or None when the files axis does.

An Option rather than a third value, and that shape is the finding rather than a detail. A gitignored file is claimed by tier two, so a three-valued tier reads naturally — but it would then have to move when Preset::All widens, and every preset moves exactly one axis per step. Files are therefore orthogonal to both axes, exactly as the / pattern is, and this says so by declining to answer rather than by answering Ignored and leaving a caller to remember not to ask.

It also no longer reads the kind, which it used to: a kind used to imply a rule, and since a gitignored file can carry one it does not.
