Enum SketchTypeExt 

#[non_exhaustive]
pub enum SketchTypeExt {
    Gaussian,
    SRHT,
    CountSketch,
    OSNAP,
    SparseJL,
}

Type of sketch matrix.

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.

Gaussian

Dense Gaussian sketch: S_{ij} ~ N(0, 1/sqrt(s)).

SRHT

Subsampled Randomized Hadamard Transform: S = sqrt(n/s) R H D.

CountSketch

Count sketch: each column mapped to one row with random sign.

OSNAP

OSNAP (Oblivious Subspace Embedding): block-diagonal sparse sketch.

SparseJL

Sparse Johnson-Lindenstrauss transform.

Trait Implementations

impl Clone for SketchTypeExt

fn clone(&self) -> SketchTypeExt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SketchTypeExt

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

Formats the value using the given formatter.

impl Default for SketchTypeExt

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SketchTypeExt

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