Struct Solver 

pub struct Solver { /* private fields */ }

Structure-exploiting convex QP solver.

Implementations

impl Solver

pub const fn new(settings: SolverSettings) -> Self

Creates a solver with explicit settings.

pub const fn settings(&self) -> &SolverSettings

Returns the active settings.

pub fn solve( &self, problem: &QpProblem, warm_start: Option<&WarmStart>, ) -> Result<Solution, SolverError>

Solves a convex factor-model QP.

When SolverSettings::scaling_iterations is positive, ADMM iterates on a Ruiz-equilibrated copy of the data; termination checks and every value on the returned Solution are evaluated on the original data.

Each call pays equilibration and factorization setup again. For rolling sequences over a fixed structure, build a Workspace with Solver::workspace instead.

Errors

Returns SolverError when the input, settings, warm start, factor covariance, or reduced linear system is invalid.

pub fn workspace(&self, problem: &QpProblem) -> Result<Workspace, SolverError>

Builds a reusable Workspace that caches the equilibration and the SMW-reduced factorization across solves (roadmap 2.4).

Use it when the problem structure — covariance, constraint matrices, bounds — is fixed and only the linear cost or right-hand sides change between solves, as in rolling rebalances.

Errors

Returns SolverError when the input, settings, factor covariance, or reduced linear system is invalid.
