Developer rewrites 65,000 lines of Go code to Rust using Fable for $400
Key points
- 65,000 lines of Go code were rewritten to Rust.
- The rewrite was performed using the Fable LLM.
- The total cost for the rewrite was $400.
- The method involved data representation, manipulation, and code generation.
The Rewrite Project
A developer undertook a project to convert a significant Go codebase into Rust. The project involved approximately 65,000 lines of code. This initiative was driven by an interest in Rust and an exploration of efficient code migration methods.
Utilizing Fable for Code Transformation
The core tool used for this large-scale rewrite was Fable, an LLM. The developer adopted a three-step methodology: first, extracting the existing Go code into a data representation (such as graphs or state machines); second, performing operations or transformations on this abstract representation; and third, generating the new code in Rust from the modified representation.
Cost and Efficiency
The entire process, including the use of the Fable LLM, incurred a cost of $400. This demonstrates a potentially cost-effective approach to large-scale language migration, especially when compared to manual rewriting efforts.
Methodology Insights
The developer noted that Fable's precision in tracing data flow was key to its effectiveness. The approach leverages the LLM's ability to handle complex refactorings and language rewrites by treating code as a data problem. This method suggests a different paradigm for code transformation, moving beyond direct code-to-code translation.

Reporting from
A developer successfully rewrote 65,000 lines of Go code into Rust using the Fable LLM for a cost of $400. This process involved extracting code into a data representation, operating on that representation, and then generating new code in Rust.
