Struct SolutionView 

pub struct SolutionView<'a> {
    pub objective: f64,
    pub primal: &'a [f64],
    pub dual: &'a [f64],
    pub reduced_costs: &'a [f64],
    pub iterations: u64,
    pub solve_time_seconds: f64,
}

Zero-copy view of an LP solution, borrowing directly from solver-internal buffers.

Valid until the next mutating method call on the solver (any &mut self call). This is enforced at compile time by the Rust borrow checker: the lifetime 'a ties the view to the solver instance that produced it.

Use SolutionView::to_owned to convert to an owned LpSolution when the solution data must outlive the current borrow, or when the same data will be accessed after a subsequent solver call.

See Solver Interface Trait SS4.1.

Fields

objective: f64

Optimal objective value (minimization sense).

primal: &'a [f64]

Primal variable values, indexed by column (length equals num_cols).

dual: &'a [f64]

Dual multipliers (shadow prices), indexed by row (length equals num_rows). Normalized to canonical sign convention.

reduced_costs: &'a [f64]

Reduced costs, indexed by column (length equals num_cols).

iterations: u64

Number of simplex iterations performed for this solve.

solve_time_seconds: f64

Wall-clock solve time in seconds (excluding retry overhead).

Implementations

impl SolutionView<'_>

pub fn to_owned(&self) -> LpSolution

Clones the borrowed slices into owned Vecs, producing an LpSolution.

Use this when the solution data must outlive the current solver borrow, or when the same solution will be read after a subsequent solver call.
