Struct IndexedCellSet 

pub struct IndexedCellSet { /* private fields */ }

A sorted, duplicate-free set of (row, output) cells in CSR form.

The representation costs O(n_rows + n_cells) and supports both sparse inclusion sets and sparse exclusion sets through StructuralCells.

Implementations

impl IndexedCellSet

pub fn new( n_rows: usize, n_outputs: usize, row_offsets: Vec<usize>, output_indices: Vec<usize>, ) -> Result<Self, IndexedResponseError>

Construct from CSR arrays. Output indices inside every row must be strictly increasing; duplicates are rejected rather than silently changing the declared response geometry.

pub fn from_cells( n_rows: usize, n_outputs: usize, cells: Vec<(usize, usize)>, ) -> Result<Self, IndexedResponseError>

Construct from unordered cell coordinates. Coordinates are sorted into canonical row-major order; duplicates remain an error.

pub fn n_rows(&self) -> usize

Number of rows in the declared response grid.

pub fn n_outputs(&self) -> usize

Number of outputs in the declared response grid.

pub fn len(&self) -> usize

Number of represented cells.

pub fn is_empty(&self) -> bool

Whether the set contains no cells.

pub fn row_outputs(&self, row: usize) -> Option<&[usize]>

Sorted output indices represented on row.

pub fn contains(&self, row: usize, output: usize) -> bool

Whether (row, output) belongs to the set.

pub fn position(&self, row: usize, output: usize) -> Option<usize>

Row-major storage position of (row, output), when present.
