Russh
Rust SSH client & server library
Russh provides a Rust library for implementing SSH clients and servers with a modern, async-friendly design. It exposes building blocks for authentication, channel management, port forwarding, and key handling, allowing you to embed SSH functionality directly into Rust applications. The API is designed to be explicit and composable, making it possible to implement custom behaviors like reverse tunnels, interactive shells, and service multiplexing. Because performance and safety are central, the code leverages Rust’s type system to reduce classes of runtime errors common in network protocol implementations. The project also includes examples and discussion threads that show how other tools integrate it for web-based clients or gateway services. For teams building terminals, proxies, or embedded management planes, it offers a robust foundation without shelling out to external binaries. -

Rust Latam
Learn to write Rust procedural macros
This is a workshop/repository by the Rust developer David Tolnay (dtolnay) intended to teach how to write Rust procedural macros (derive macros, function-like macros, attribute macros). The repo contains multiple toy/realistic macro projects drawn from real use-cases: e.g., derive(Builder), derive(CustomDebug), seq!, #[sorted], #[bitfield]. The README indicates the focus is on learning: parsing token streams, generating code, handling generics, attribute arguments, etc. It has test harness and workflow guidance. Because procedural macros are quite subtle in Rust, this workshop is a strong resource for anyone wanting to go from beginner to intermediate/advanced macro writing. -

Rust-Lightning
Bitcoin Lightning library written in Rust
Rust-Lightning is a Bitcoin Lightning library written in Rust. The main crate, lightning, does not handle networking, persistence, or any other I/O. Thus, it is runtime-agnostic, but users must implement basic networking logic, chain interactions, and disk storage. The project implements all of the BOLT specifications in the 1.0 spec. The implementation has pretty good test coverage that is expected to continue to improve. It is also anticipated that as developers begin using the API, the lessons from that will result in changes to the API, so any developer using this API at this stage should be prepared to embrace that. LDK/Rust-Lightning is a generic library which allows you to build a lightning node without needing to worry about getting all of the lightning state machine, routing, and on-chain punishment code (and other chain interactions) exactly correct. Note that Rust-Lightning isn't, in itself, a node. -

Svix
The enterprise-ready webhooks service
Build a secure, reliable, and scalable webhook platform in minutes using the Svix webhook service. Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect. Building a secure, reliable, and scalable webhook service is hard and time-consuming. We built it so you can focus on what matters most, your business. Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability. You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers. Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events. You would need to build a UI for your users to add and remove endpoints, inspect logs and get ongoing reports. Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks. -

async-graphql
A GraphQL server library implemented in Rust
Async-graphql is a GraphQL server-side library implemented in Rust. It is fully compatible with the GraphQL specification and most of its extensions and offers type safety and high performance. You can define a Schema in Rust and procedural macros will automatically generate code for a GraphQL query. This library does not extend Rust's syntax, which means that Rustfmt can be used normally. I value this highly and it is one of the reasons why I developed Async-graphql. I like GraphQL and Rust. I've been using Juniper, which solves the problem of implementing a GraphQL server with Rust. But Juniper had several problems, the most important of which is that it didn't support async/await at the time. So I decided to make this library for myself. -

derive(Error)
derive(Error) for struct and enum error types
This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this error is not a breaking change: you retain the same API. The README shows examples: an enum with variants annotated by #[error("…")] and #[from] fields to derive the appropriate trait impls. The crate expects rustc ≥ 1.68+. The README also outlines how you choose; use thiserror if you care about designing your own error-types (e.g., for libraries) vs anyhow for applications. -

glium
Safe OpenGL wrapper for the Rust language
Glium is a safe OpenGL wrapper for the Rust programming language, aiming to combine the low-level control of OpenGL with Rust's safety and concurrency features. It provides an idiomatic Rust API for OpenGL functions, ensuring that graphics programming is both safe and efficient. Glium abstracts many of the unsafe aspects of OpenGL, reducing the likelihood of runtime errors and crashes. -

hyper for Rust
An HTTP library for Rust
hyper is a fast HTTP implementation written in and for Rust. A Client for talking to web services. A Server for building those web services. Blazing fast thanks to Rust. High concurrency with non-blocking sockets. HTTP/1 and HTTP/2 support. hyper is a relatively low-level library, meant to be a building block for libraries and applications. If you are looking for a convenient HTTP client, then you may wish to consider reqwest. If you are looking for a convenient HTTP server, then you may wish to consider warp. Both are built on top of this library. A Service lets you define how to respond to incoming requests. While it is possible to implement the trait directly, there are a few patterns that are common when using Hyper. We’ve included some helpers for when these patterns fit our needs. An echo server will listen for incoming connections and send back the request body as the response body on POST requests. -

rust_cmd_lib
Common rust command-line macros and utilities
rust_cmd_lib is a Rust library designed to make it easier to write shell-script–style tasks in Rust, blending the power and safety of Rust with the expressiveness of shell pipelines. It provides macros and utilities that let you spawn external processes, redirect input/output, and pipe commands together, all without invoking a shell. You can write something like run_cmd!(ls -l | grep foo > out.txt) in a more declarative style, rather than manually wiring up file descriptors, handles, and child processes. The library also supports features like variable substitution, scoped environment settings, and defining custom commands (functions) that behave like built-ins. It hides much of the boilerplate of std::process::Command when you're doing simple task automations, but still allows full flexibility when needed. Because it avoids launching a shell, it reduces some classes of security and quoting errors, while improving readability of scripting logic inside a Rust binary. -

rustdesk-server-demo
A working demo of RustDesk server implementation
rustdesk-server-demo is a companion repository that demonstrates how to deploy the RustDesk backend quickly, often via containerized or scripted setups. It is intended as a practical starting point for testing and small-scale pilots before moving to a hardened production configuration. The demo showcases the interplay between the rendezvous and relay components so users can validate connectivity paths end-to-end. Clear defaults minimize the amount of configuration required, making first-time evaluations straightforward. Because it mirrors the structure of a typical deployment, it helps administrators understand networking requirements, ports, and service boundaries. It’s a helpful on-ramp for teams who want to confirm RustDesk fits their environment before investing in a full rollout. -

winit
Window handling library in pure Rust
Cross-platform window creation and management in Rust. Winit is a window creation and management library. It can create windows and lets you handle events (for example the window being resized, a key being pressed, a mouse movement, etc.) produced by the window. Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to show something on the window you need to use the platform-specific getters provided by winit, or another library.
