Enum UpdateType 

#[non_exhaustive]
pub enum UpdateType {
    RankOneUpdate,
    RankOneDowndate,
    LowRankUpdate,
}

Classification of Cholesky modification types.

Describes the kind of rank-structured perturbation applied to the original matrix A = L L^T.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RankOneUpdate

Rank-1 update: A’ = A + α u u^T (α > 0).

RankOneDowndate

Rank-1 downdate: A’ = A − α u u^T (α > 0).

LowRankUpdate

Low-rank update: A’ = A + W D W^T where D is diagonal.

Trait Implementations

impl Clone for UpdateType

fn clone(&self) -> UpdateType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for UpdateType

impl Debug for UpdateType

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

Formats the value using the given formatter.

impl Display for UpdateType

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

Formats the value using the given formatter.

impl Eq for UpdateType

impl Hash for UpdateType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UpdateType

fn eq(&self, other: &UpdateType) -> 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.
