Enum SparseMask 

pub enum SparseMask {
    Empty,
    Single {
        word_index: usize,
        mask: u64,
    },
    Multi {
        indices: Vec<usize>,
        masks: Vec<u64>,
    },
}

Sparse enablement mask: precomputed for efficient bitmap checks.

Variants

Empty

No bits set (e.g. no inputs / no inhibitors).

Single

Exactly one non-zero word at the given index.

Fields

word_index: usize

mask: u64

Multi

Multiple non-zero words (sparse representation).

Fields

indices: Vec<usize>

masks: Vec<u64>
