Questions tagged [rust-tokio]

Tokio aims to be:

• Fast: Tokio's zero-cost abstractions give you bare-metal performance.

• Productive: Tokio makes it easy to implement protocols and program asynchronously.

• Reliable: Tokio leverages Rust's ownership and concurrency model to ensure thread safety.

• Scalable: Tokio has a minimal footprint, and handles backpressure and cancellation naturally.

At a high level, it provides a few major components:

• A multithreaded, work-stealing based task scheduler.
• A reactor backed by the operating system's event queue (epoll, kqueue, IOCP, etc...).
• Asynchronous TCP and UDP sockets.
