Async runtime
An async runtime is software that schedules asynchronous tasks and drives their suspended computations toward completion.
Rust Servers, Services, and Apps
An asynchronous runtime is software that schedules and executes nonblocking asynchronous operations and tasks.
- How it is used
- Schedules I/O-waiting tasks so web services can continue processing other work.
- How deep it goes
- Explains executor polling, waking, and a custom timer Future, while deferring a full explanation of pinning.
- Examples
- Contrasts simulated sequential and concurrent file reads, then builds a timer Future with an expiration time.
- What you can do after
- Apply it via Tokio: spawn and join async tasks, then implement a Future that wakes the executor when ready.

An async runtime is software that schedules asynchronous tasks, drives Future polling, and determines when suspended computations are polled again.
- How it is used
- Manages Future polling and provides the execution boundary required to run asynchronous Rust code.
- How deep it goes
- Explains Pending and Ready, await placement, macro behavior, and runtime expansion, but does not develop runtime internals.
- Examples
- Uses async_give_8, compiler errors, Tokio macro expansion, and a reqwest HTTP request.
- What you can do after
- Operate asynchronous Rust programs with Tokio, .await, async functions, and runtime-managed program entry points.
