SolverPlan

eqiora::solver

Struct SolverPlan 

pub struct SolverPlan { /* private fields */ }
Description

Complete numerical policy for one linear solve.

This is the only solver-control type. Numerical realization crates consume it directly; they do not translate it into method-specific configuration.

Implementations§

§

impl SolverPlan

Signature links:§SolverPlan

pub fn new( algorithm: LinearSolver, relative_tolerance: f64, absolute_tolerance: f64, maximum_iterations: NonZero<usize>, ) -> Result<SolverPlan, Diagnostic>

Signature links:newLinearSolverf64f64NonZerousizeResultSolverPlanDiagnostic

Construct a validated plan with identity preconditioning and a reproducible reduction policy.

§Errors

Returns EQ0807 for non-finite, negative, or jointly zero tolerances.

pub const fn with_preconditioner( self, preconditioner: PreconditionerPolicy, ) -> SolverPlan

Signature links:with_preconditionerPreconditionerPolicySolverPlan

Select a preconditioner without changing the other controls.

pub const fn with_reduction(self, reduction: ReductionPolicy) -> SolverPlan

Signature links:with_reductionReductionPolicySolverPlan

Select a reduction policy without changing the other controls.

pub const fn algorithm(self) -> LinearSolver

Signature links:algorithmLinearSolver

Solver algorithm.

pub const fn preconditioner(self) -> PreconditionerPolicy

Signature links:preconditionerPreconditionerPolicy

Preconditioner policy.

pub const fn reduction(self) -> ReductionPolicy

Signature links:reductionReductionPolicy

Floating-point reduction policy.

pub const fn relative_tolerance(self) -> f64

Signature links:relative_tolerancef64

Relative convergence tolerance.

pub const fn absolute_tolerance(self) -> f64

Signature links:absolute_tolerancef64

Absolute convergence tolerance.

pub const fn maximum_iterations(self) -> NonZero<usize>

Signature links:maximum_iterationsNonZerousize

Iteration limit or direct-solve work bound.

The eqiora.reference minimum-residual implementation caps its retained full-H projection at the smaller of this value and the operator dimension. Other providers interpret this common bound independently.

Sparse LU retains this field as part of the common plan identity, ignores it as a factorization control, and reports at most one completed factor-and-solve attempt.

pub fn residual_target( self, right_hand_side_norm: f64, ) -> Result<f64, Diagnostic>

Signature links:residual_targetf64Resultf64Diagnostic

Accepted Euclidean residual threshold for a right-hand-side norm.

§Errors

Returns EQ0802 if the norm is negative/non-finite or the target overflows.
