Struct SparsityMetadata 

pub struct SparsityMetadata {
    pub active_chunks: Vec<u64>,
    pub chunk_size: usize,
    pub num_chunks: usize,
}

Sparsity metadata for efficient plane skipping.

Tracks which chunks of dimensions are entirely zero, enabling the kernel to skip computation for those regions.

Fields

active_chunks: Vec<u64>

Bitmap of active chunks (bit set if chunk has non-zero elements). Each bit represents chunk_size consecutive dimensions.

chunk_size: usize

Size of each chunk in dimensions.

num_chunks: usize

Total number of chunks.

Implementations

impl SparsityMetadata

pub fn from_planes( planes: &TernaryPlanes, chunk_size: usize, ) -> SparsityMetadata

Create metadata from ternary planes.

pub fn is_chunk_active(&self, chunk_idx: usize) -> bool

Check if a specific chunk is active.

pub fn active_count(&self) -> usize

Count active chunks.

pub fn chunk_sparsity(&self) -> f32

Effective sparsity (fraction of inactive chunks).
