//! The Rerun chunk store, implemented on top of [Apache Arrow](https://arrow.apache.org/)
//! using the [`arrow2`] crate.
//!
//! This crate is an in-memory time series database for Rerun log data.
//! It is indexed by Entity path, component, timeline, and time.
//! It supports out-of-order insertions, and fast `O(log(N))` queries.
//!
//! * See [`ChunkStore`] for an overview of the core data structures.
//! * See [`ChunkStore::latest_at_relevant_chunks`] and [`ChunkStore::range_relevant_chunks`]
//!   for the documentation of the public read APIs.
//! * See [`ChunkStore::insert_chunk`] for the documentation of the public write APIs.
//!
//! ## Feature flags
#![doc = document_features::document_features!()]
