Struct PredicateEntry 

pub struct PredicateEntry {
    pub arg_index: FnvHashMap<FirstArgKey, Vec<usize>>,
    pub var_clause_indices: Vec<usize>,
    pub all_clause_indices: Vec<usize>,
}

Entry for a single predicate (functor/arity). Supports two-tier indexing: functor/arity lookup, then first-argument hash.

Fields

arg_index: FnvHashMap<FirstArgKey, Vec<usize>>

First-argument index: ground first arg -> clause indices

var_clause_indices: Vec<usize>

Clause indices where the first arg is a variable (must always be included)

all_clause_indices: Vec<usize>

All clause indices in source order (fallback)
