Module knn 

Re-export and PaCMAP-facing adapters for flow_knn.

Structs

KnnGraph

Portable k-nearest-neighbour graph: per-point indices and distances only.

NeighborList

Neighbours of a single query point.

PerfRecord

One timed cell in the (n, d, method) performance matrix.

RecommendOpts

Preferences that bias automatic method choice.

Functions

builtin_matrix

Built-in snapshot used when JSONL parse fails.

compute_knn

Compute k nearest neighbours for all n points in data (n×d row-major).

load_matrix

Load matrix: prefer path if readable, else the shipped JSONL / builtin_matrix.

parse_matrix_jsonl

Parse JSONL text into records (skips blank / comment lines).

read_knn_graph

Read a KnnGraph previously written by write_knn_graph.

recommend_method

Recommend a KnnMethod for n points of dimension d.

recommend_method_with_matrix

Same as recommend_method but with an explicit matrix (tests / custom datasets).

validate_knn_for_pacmap

Validate a graph for PaCMAP, mapping flow_knn::KnnError into PaCMAPError.

write_knn_graph

Write a KnnGraph to path (creates/overwrites the file).
