Struct IpmOptions 

pub struct IpmOptions {
    pub max_iter: usize,
    pub eps: f64,
    pub delta_min: f64,
    pub delta_p_init: f64,
    pub delta_d_init: f64,
    pub max_correctors: usize,
    pub dd_ldl: bool,
    /* private fields */
}

IPM (interior-point method) solver options.

Set via SolverOptions::ipm. Call IpmOptions::validate (or SolverOptions::validate) before solving to catch invalid values early.

Fields

max_iter: usize

Total IPM iterations across all attempts. Default: usize::MAX (timeout is the primary guard).

Each attempt is internally capped at MAX_ITER_PER_ATTEMPT (currently 500); this field is the cumulative budget across all retry attempts.

eps: f64

Convergence tolerance. Default: DEFAULT_IPM_EPS.

delta_min: f64

Proximity regularisation lower bound δ_min. Default: DEFAULT_IPM_DELTA_MIN.

delta_p_init: f64

Initial primal proximity regularisation δ_p. Default: DEFAULT_IPM_DELTA_INIT.

delta_d_init: f64

Initial dual proximity regularisation δ_d. Default: DEFAULT_IPM_DELTA_INIT.

max_correctors: usize

Maximum Gondzio correctors. Default: DEFAULT_IPM_MAX_CORRECTORS.

dd_ldl: bool

Use TwoFloat (double-double, ~106-bit) LDL for KKT systems where f64 conditioning would exceed the requested accuracy. Default: false.

Implementations

impl IpmOptions

pub fn validate(&self) -> Result<(), OptionsError>

Validate all numeric fields.

Returns the first Err in field declaration order. Invalid: non-finite or non-positive eps / delta_*, or max_correctors == 0.

pub fn with_eps(self, eps: f64) -> Result<Self, OptionsError>

Builder: set eps, validated immediately.

pub fn with_max_correctors(self, n: usize) -> Result<Self, OptionsError>

Builder: set max_correctors, validated immediately.

Trait Implementations

impl Clone for IpmOptions

fn clone(&self) -> IpmOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IpmOptions

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

Formats the value using the given formatter.

impl Default for IpmOptions

fn default() -> Self

Returns the “default value” for a type.
