Struct CharSet 

pub struct CharSet {
    pub predicates: Vec<u32>,
    pub subjects: u64,
}

A characteristic set — one entity “shape”: the sorted set of predicates a subject carries, plus how many subjects share exactly that shape. Computed at build (top-N shapes by subject count), range-fetched with the pyramid. Useful for data profiling (the distinct entity shapes) and for estimating the selectivity of a subject star (subjects matching ALL of several predicates).

Fields

predicates: Vec<u32>

Predicate ids, ascending.

subjects: u64

Subjects whose predicate set is exactly this.
