Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Requires understanding of Rust's ownership and borrowing system, which can be complex for those coming from other languages
Smaller user base means fewer resources and slower response times for issues and feature requests
Requires setting up Rust toolchain, Node.js environment, and potentially additional dependencies like CMake or Cargo
While Rust offers performance benefits, the overhead of crossing language boundaries can introduce latency in certain scenarios
