Research direction
This issue requires replacing the discontinued async std crate with the suggested alternative, smol. First, review the advisory and understand any API differences. Then, search the codebase for all imports and usage of async std (e.g., in Cargo.toml and source files). Replace with smol equivalents, ensuring compatibility with the existing async runtime (likely tokio if used elsewhere). Run the full test suite and verify no regressions. If tests fail, consult the smol documentation or community for guidance.
