Struct Inertia 

pub struct Inertia {
    pub positive: usize,
    pub zero: usize,
    pub negative: usize,
}

Inertia of a symmetric matrix (count of positive / zero / negative eigenvalues). Used by bump_with_matrix and other indefinite-aware stabilization rules to drive δ from spectral evidence rather than a condition-number heuristic.

Fields

positive: usize

zero: usize

negative: usize

Trait Implementations

impl Clone for Inertia

fn clone(&self) -> Inertia

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Inertia

impl Debug for Inertia

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Inertia

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Inertia

impl PartialEq for Inertia

fn eq(&self, other: &Inertia) -> 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 Inertia

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
