async-std is a Rust crate providing an async version of the Rust standard library, with async/await-compatible APIs for tasks, networking, and file access. It has been officially discontinued and deprecated in favor of the smol project.

Use cases

• write async Rust code with std-like APIs
• run async tasks with an executor in Rust
• async networking and file I/O in Rust
• learn async/await in Rust with familiar stdlib interfaces
• maintain legacy Rust code that depends on async-std

When to choose

• you are maintaining an existing codebase already built on async-std
• you need stdlib-parity async APIs in a legacy Rust project

When to avoid

• you are starting a new Rust project - use smol or tokio instead
• you need a maintained async runtime with ongoing support
• you want long-term ecosystem compatibility
