Tokio - An asynchronous Rust runtime (original) (raw)
Build reliable network applications without compromising speed.
Tokio is an asynchronous runtime for the Rust programming language. It provides the building blocks needed for writing network applications. It gives the flexibility to target a wide range of systems, from large servers with dozens of cores to small embedded devices.
Tokio's APIs are memory-safe, thread-safe, and misuse-resistant. This helps prevent common bugs, such as unbounded queues, buffer overflows, and task starvation.
Building on top of Rust, Tokio provides a multi-threaded, work-stealing scheduler. Applications can process hundreds of thousands of requests per second with minimal overhead.
async/await reduces the complexity of writing asynchronous applications. Paired with Tokio's utilities and vibrant ecosystem, writing applications is a breeze.
The needs of a server application differ from that of an embedded device. Although Tokio comes with defaults that work well out of the box, it also provides the knobs needed to fine tune to different cases.
Applications aren't built in a vacuum. The Tokio stack includes everything needed to ship to production, fast.
Including I/O, timer, filesystem, synchronization, and scheduling facilities, the Tokio runtime is the foundation of asynchronous applications.
