#data-structures

Blazing fast immutable collection datatypes for Rust.

A high-performance, lock-free price level implementation for limit order books in Rust. This library provides the building blocks for creating efficient trading systems with support for multiple order types and concurrent access patterns.

An Approximate Nearest Neighbors library in Rust, based on random projections and LMDB and optimized for memory usage :boom:

PQC-secure gossip overlay network for Communitas

A Rust library that turns Markdown into WCAG-compliant, SEO-friendly HTML — front matter, TOC, JSON-LD, MathML, Mermaid, and minification in one pipeline. Runs natively or as WebAssembly.

High-performance wait-free memory reclamation for wait-free data structures (ASMR). Bounded memory usage, predictable latency.

An append-only merkle tree which is always pruned, along with incremental, fast-forwarding witnesses

More efficient alternative to `serde_json::Value` which saves memory by interning primitive values and using tagged pointers.
