Enum EstimationMethod 

pub enum EstimationMethod {
    UpperBound,
    Exact,
    Sampling {
        sample_count: usize,
    },
}

The method used for SpGEMM nnz estimation.

Variants

UpperBound

Per-row upper bound summing nnz of accessed B-rows.

Exact

Exact count using hash sets (or bitsets for narrow matrices).

Sampling

Sampling-based estimate with the given number of sampled rows.

Fields

sample_count: usize

Number of rows actually sampled.

Trait Implementations

impl Clone for EstimationMethod

fn clone(&self) -> EstimationMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EstimationMethod

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

Formats the value using the given formatter.

impl Eq for EstimationMethod

impl PartialEq for EstimationMethod

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