Enum OptimizationCriterion 

pub enum OptimizationCriterion {
    MinLatency,
    MaxRecall,
    MinMemory,
    Balanced,
    CostBudget(u64),
}

Criterion used to compare and select index structures.

Variants

MinLatency

Minimise query latency.

MaxRecall

Maximise recall@k.

MinMemory

Minimise memory usage.

Balanced

Balanced trade-off between latency, recall, and memory.

CostBudget(u64)

Stay within a hard memory budget (bytes).

Trait Implementations

impl Clone for OptimizationCriterion

fn clone(&self) -> OptimizationCriterion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptimizationCriterion

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

Formats the value using the given formatter.

impl PartialEq for OptimizationCriterion

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