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 non-Rust developers

   The tool is implemented in Rust, which may be unfamiliar to many developers accustomed to more mainstream languages like Python or JavaScript.

2. 02

   Limited community and support

   Being a niche project with a smaller user base means fewer resources for troubleshooting and less active development of features compared to larger, more established projects.

3. 03

   Poor documentation

   The official documentation is sparse and lacks comprehensive examples or tutorials, making it difficult for new users to get started without significant trial and error.

4. 04

   Complex setup process

   Setting up the environment requires a deep understanding of Rust tooling and dependencies, which can be time-consuming and challenging for those not familiar with Rust's ecosystem.

What it does well

• Pure Rust implementation for performance and efficiency

• Minimalistic design for lightweight deployment
