Struct RowBatch 

pub struct RowBatch {
    pub num_rows: usize,
    pub row_starts: Vec<i32>,
    pub col_indices: Vec<i32>,
    pub values: Vec<f64>,
    pub row_lower: Vec<f64>,
    pub row_upper: Vec<f64>,
}

Batch of constraint rows for addition to a loaded LP, in CSR (row-major) form.

Assembled from the row-pool activity bitmap before each LP rebuild and passed to crate::SolverInterface::add_rows for a single batch call. Rows are appended at the bottom of the constraint matrix in the dynamic constraint region per Solver Abstraction SS2.2.

See Solver Interface Trait SS4.5 and the row-pool assembly protocol in Solver Abstraction SS5.4.

Fields

num_rows: usize

Number of active constraint rows in this batch.

row_starts: Vec<i32>

CSR row start offsets (i32 for HiGHS FFI compatibility).

Length: num_rows + 1. Entry row_starts[i] is the index into col_indices and values where row i begins. row_starts[num_rows] equals the total number of non-zeros.

col_indices: Vec<i32>

CSR column indices for each non-zero entry (i32 for HiGHS FFI compatibility).

Length: total non-zeros across all rows. Entry col_indices[k] is the column of the k-th non-zero value.

values: Vec<f64>

CSR non-zero values.

Length: total non-zeros across all rows. Entry values[k] is the coefficient at column col_indices[k] in its row.

row_lower: Vec<f64>

Row lower bounds (RHS lower bounds for >= constraints).

Length: num_rows. For >= constraints, this is the RHS lower bound.

row_upper: Vec<f64>

Row upper bounds.

Length: num_rows. Use f64::INFINITY for >= constraints (no finite upper bound).

Implementations

impl RowBatch

pub fn clear(&mut self)

Reset all buffers to empty without deallocating.

After clear(), num_rows is 0 and all Vec fields have length 0 but retain their allocated capacity for reuse.

Trait Implementations

impl Clone for RowBatch

fn clone(&self) -> RowBatch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RowBatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
