Enum NormalizationHint 

pub enum NormalizationHint {
    Unknown,
    Unit,
}

Caller assertion that a vector is L2-unit-normalized (norm ≈ 1).

When both query and stored vectors carry UnitNorm, cosine similarity equals the dot product — the norm division can be skipped entirely.

Variants

Unknown

No guarantee — full cosine (with norm division) is required.

Unit

Caller asserts this vector is L2-unit-normalized (norm ≈ 1 within 1e-4).

Trait Implementations

impl Clone for NormalizationHint

fn clone(&self) -> NormalizationHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NormalizationHint

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

Formats the value using the given formatter.

impl PartialEq for NormalizationHint

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