Enum StabilizationRule 

pub enum StabilizationRule {
    FixedConstant,
    InertiaTarget {
        spd_floor: f64,
    },
    Heuristic,
    UserSpecified,
    BackoffEscalation {
        attempts: usize,

}

Why a stabilization δ was chosen at this site.

Variants

FixedConstant

δ is a hard-coded constant in the source.

InertiaTarget

δ chosen so the SPD floor τ is met: δ = max(0, τ - λ_min(H)).

Fields

spd_floor: f64

Heuristic

δ chosen via a condition-number / sqrt-ratio heuristic.

UserSpecified

User- or family-specified prior precision.

BackoffEscalation

δ derived from a back-off escalation after a factorization failure.

Fields

attempts: usize

Trait Implementations

impl Clone for StabilizationRule

fn clone(&self) -> StabilizationRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StabilizationRule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StabilizationRule

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StabilizationRule

fn eq(&self, other: &StabilizationRule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StabilizationRule

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
