Overview

For each of Rust and Dart, we support the synchronous and asynchronous grammar. The combinations, with brief explanations of its semantics, are listed as follows:

• Async Dart + Sync Rust: Dart is non-blocking, Rust uses thread pool
• Async Dart + Async Rust: Dart is non-blocking, Rust uses async runtime
• Sync Dart + Sync Rust: Dart is blocking, Rust is executed on main thread
• Sync Dart + Async Rust (not very reasonable)
