Struct CooBuilder 

pub struct CooBuilder { /* private fields */ }

Implementations

impl CooBuilder

pub fn new(n: usize) -> Self

Square n × n accumulator.

pub fn with_capacity(n: usize, capacity: usize) -> Self

Square n × n accumulator with a pre-sized entry table.

pub fn new_rect(rows: usize, cols: usize) -> Self

Rectangular rows × cols accumulator.

pub fn with_capacity_rect(rows: usize, cols: usize, capacity: usize) -> Self

Rectangular rows × cols accumulator with a pre-sized entry table.

pub fn n(&self) -> usize

Side length for a square builder (row count in general).

pub fn shape(&self) -> (usize, usize)

(rows, cols).

pub fn add(&mut self, i: usize, j: usize, v: f64)

Accumulate v into entry (i, j). Skips the insert if v == 0.0.

pub fn add_sym(&mut self, i: usize, j: usize, v: f64)

Symmetrically accumulate v into both (i, j) and (j, i). Square builders only.

pub fn finish_csr(self) -> CsMat<f64>

Materialize as a CsMat<f64> (CSR) with explicit zeros pruned.

pub fn finish_csc(self) -> CsMat<f64>

Materialize as a CSC matrix.
