Fast sorted collections for Swift using in-memory B-trees

This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.

Python tree data library

ConcurrentQueue is a header-only C++ template library that provides a lock-free data structure for multi-producer multi-consumer thread communication. It functions as a synchronization primitive designed to coordinate data flow between concurrent execution units using atomic operations rather than traditional mutex locking. The library distinguishes itself through a design that minimizes contention and synchronization overhead. It utilizes sub-queue token mapping to distribute workloads across partitioned internal queues and supports bulk operations to transfer multiple data elements in singl

Python dictionaries with advanced dot notation access

This Java concurrency library provides a suite of tools for managing multi-threaded execution, synchronization, and memory consistency. It serves as a comprehensive framework for implementing concurrent execution through lock-free atomics, thread-safe collections, task coordination primitives, and worker pools. The project includes a dedicated thread synchronization toolkit featuring latches, barriers, and semaphores to coordinate the timing and order of concurrent tasks. It also provides a concurrent collection suite of maps, queues, and lists that enable data sharing without manual locking,

A Graph Library for Swift

A Generic Priority Queue in Pure Swift

This project is a set theory library for Go that provides a data structure for storing unique elements of any comparable type using generics. It serves as a tool for managing unique collections and performing mathematical operations such as intersections and differences. The library provides synchronized collections to prevent data races during concurrent read and write operations. It also supports converting unique collections to and from JSON arrays for data persistence and network transmission. The implementation covers membership testing, collection cloning, and size calculation. It incl
