About Tokio
From the project's README at github.com/tokio-rs/tokio. Lightly cleaned for readability; for the full source see the upstream repo.
A runtime for writing reliable, asynchronous, and slim applications with the Rust programming language. It is:
Fast: Tokio's zero-cost abstractions give you bare-metal performance.
Reliable: Tokio leverages Rust's ownership, type system, and concurrency model to reduce bugs and ensure thread safety.
Scalable**: Tokio has a minimal footprint, and handles backpressure and cancellation naturally.
