Struct DocLengths 

pub struct DocLengths { /* private fields */ }

Document length table for BM25 normalization. Stores the token count for each node’s content indexed by node ID (dense array).

Implementations

impl DocLengths

pub fn new() -> Self

Create an empty doc lengths table.

pub fn build(graph: &MemoryGraph, tokenizer: &Tokenizer) -> Self

Build from graph — tokenize all content and count tokens.

pub fn get(&self, node_id: u64) -> u32

Get token count for a node.

pub fn average(&self) -> f32

Average document length.

pub fn len(&self) -> usize

Number of documents with non-zero length.

pub fn is_empty(&self) -> bool

Whether the table is empty.

pub fn add_node(&mut self, event: &CognitiveEvent)

Add a single node’s document length.

pub fn remove_node(&mut self, id: u64)

Remove a node’s document length.

pub fn clear(&mut self)

Clear all lengths.

pub fn rebuild(&mut self, graph: &MemoryGraph)

Rebuild from a graph.

pub fn to_bytes(&self) -> Vec<u8>

Serialize to bytes for file writing.

pub fn from_bytes(data: &[u8]) -> Option<Self>

Deserialize from bytes.
