Tokio
The async runtime powering most of Rust's networked, concurrent, and I/O-bound applications.
tokio-tungstenite
Asynchronous, Tokio-native WebSocket streams built on tungstenite
backoff
Python function decorators that retry calls on exceptions or bad return values, with exponential, fibonacci, or constant backoff and jitter.
tree-sitter-cpp
A fast, incremental C++ grammar for the tree-sitter parsing library
Tornado
Python web framework and asynchronous networking library built for high concurrency
bb8
A full-featured async connection pool for Rust, built on Tokio.
NVIDIA NCCL
Optimized primitives for collective multi-GPU and multi-node communication
bon
Compile-time-checked builder generator and named function arguments for Rust
mysql_async
An asynchronous, Tokio-based MySQL client library for Rust with connection pooling, prepared statements, and pluggable TLS.
queue
Tiny, dependency-free async queue with concurrency control — faster and smaller than p-limit or fastq, with optional rate limiting.
aiocsv
Asynchronous CSV reading and writing for Python's asyncio, with a drop-in-compatible API and an optional C-accelerated parser.
ANTLR4 Python3 Runtime
The Python 3 runtime that generated ANTLR parsers and lexers depend on at execution time.
conan
The decentralized, open-source package manager for C and C++.
react-final-form
A thin React wrapper for Final Form, a subscriptions-based form state manager that re-renders only the fields whose state actually changed.
mio
