Replace discontinued async-std with smol runtime (RUSTSEC-2025-0052)

Open Copilot opened this issue 6 months ago • 1 comments

This PR addresses the security advisory RUSTSEC-2025-0052 by migrating from the discontinued async-std crate to the actively maintained smol runtime.

Background

The async-std crate has been discontinued as of 2025-08-24. The project is now unmaintained, and the Rust Security Advisory Database recommends migrating to alternative async runtimes like smol.

Changes

The migration involved minimal changes to maintain compatibility:

Cargo.toml:

- async-std = "1.9"
+ smol = "2.0"

src/main.rs:

- #[async_std::main]
- async fn main() {
+ fn main() {
+     smol::block_on(async {
          // ... existing async code ...
-         let _handle = async_std::task::spawn(async move {
+         let _handle = smol::spawn(async move {
              // ... existing task code ...
          });
          // ... rest of async code ...
+     })
  }

Verification

✅ Application builds successfully in both debug and release modes
✅ All async functionality (browser handling, task spawning) works correctly
✅ Command-line interface and core fuzzing logic remain unchanged
✅ No breaking changes to the public API

The smol runtime is a lightweight, actively maintained async executor that provides equivalent functionality to async-std while being more performant and better maintained.

Fixes #52.
