Enum FallbackPath 

#[repr(u8)]
pub enum FallbackPath {
    None = 0,
    NProbeWidened = 1,
    DegenerateWidened = 2,
    SafetyNetSelective = 3,
    SafetyNetBudgetExhausted = 4,
}

Which fallback path was chosen during query execution.

Variants

None = 0

Normal HNSW traversal, no fallback needed.

NProbeWidened = 1

Adaptive n_probe widening due to epoch drift.

DegenerateWidened = 2

Adaptive n_probe widening due to degenerate distribution.

SafetyNetSelective = 3

Selective safety net scan on hot cache.

SafetyNetBudgetExhausted = 4

Safety net budget exhausted before completion.

Trait Implementations

impl Clone for FallbackPath

fn clone(&self) -> FallbackPath

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FallbackPath

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

Formats the value using the given formatter.

impl Hash for FallbackPath

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 FallbackPath

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