Enum TreeGrouping 

#[non_exhaustive]
pub enum TreeGrouping {
    Level(u32),
    Depth,
}

What a tree grouping keeps of an ltree path (#1498).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Level(u32)

The first n labels (subpath(path, 0, n)); a shorter path is kept whole.

Depth

The number of labels (nlevel(path)).
