Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Steep learning curve for developers unfamiliar with Rust

   Requires understanding of Rust's ownership and borrowing system, which can be complex for those coming from other languages

2. 02

   Limited community support compared to more established frameworks

   Smaller user base means fewer resources and slower response times for issues and feature requests

3. 03

   Complex setup process involving multiple build tools

   Requires setting up Rust toolchain, Node.js environment, and potentially additional dependencies like CMake or Cargo

4. 04

   Performance overhead due to FFI (Foreign Function Interface) calls

   While Rust offers performance benefits, the overhead of crossing language boundaries can introduce latency in certain scenarios

What it does well

• Simplified Rust bindings for Node.js APIs

• Safety and performance benefits of Rust

• Compatibility with the latest Node.js versions
