Struct IndexFragmentStats 

pub struct IndexFragmentStats {
    pub total_vectors: usize,
    pub deleted_vectors: usize,
    pub index_bytes: u64,
}

Statistics describing the fragmentation state of a single HNSW index.

Fields

total_vectors: usize

Total number of vector slots (live + deleted).

deleted_vectors: usize

Number of slots marked as deleted but not yet reclaimed.

index_bytes: u64

Estimated on-disk / in-memory footprint in bytes.

Implementations

impl IndexFragmentStats

pub fn new( total_vectors: usize, deleted_vectors: usize, index_bytes: u64, ) -> Self

Creates a new IndexFragmentStats.

pub fn deleted_ratio(&self) -> f64

Ratio of deleted vectors to total vectors.

Returns 0.0 when total_vectors == 0 to avoid division-by-zero.

pub fn live_vectors(&self) -> usize

Number of live (non-deleted) vectors.

Trait Implementations

impl Clone for IndexFragmentStats

fn clone(&self) -> IndexFragmentStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexFragmentStats

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

Formats the value using the given formatter.

impl PartialEq for IndexFragmentStats

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