Struct IndexStats 

pub struct IndexStats {
    pub chunks: usize,
    pub files: usize,
    pub vectors: Option<usize>,
    pub by_language: Vec<(Language, usize)>,
    pub by_kind: Vec<(ChunkKind, usize)>,
    pub embedder: String,
    pub store: String,
}

A breakdown of what an index currently holds.

Fields

chunks: usize

files: usize

vectors: Option<usize>

Vectors held by the store, when one is open. Should track chunks; a gap means the store and the chunk metadata have drifted apart. None after a metadata-only read, where the store was never loaded.

by_language: Vec<(Language, usize)>

Chunk counts per language, most frequent first.

by_kind: Vec<(ChunkKind, usize)>

Chunk counts per kind, most frequent first.

embedder: String

Fingerprint of the embedder that produced the vectors.

store: String

Fingerprint of the store holding them, i.e. its distance metric.

Implementations

impl IndexStats

pub fn open(index_dir: &Path) -> Result<Self, RagError>

Summarize the index at index_dir from its metadata alone.

Reads the chunk registry and the manifest, and nothing else: no embedding model is loaded and no vectors are touched, so inspecting an index costs milliseconds. The trade-off is that vectors stays None, because only the store knows how many it holds.

Trait Implementations

impl Clone for IndexStats

fn clone(&self) -> IndexStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexStats

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

Formats the value using the given formatter.
