Question 1

How do I embed Starlark in my Rust app?

Accepted Answer

Use the main starlark library to integrate Starlark by defining custom types and functions in Rust, then embed the evaluator; the README suggests writing your own binary for domain-specific features.

Question 2

Starlark-rust vs Starlark-go for a new project?

Accepted Answer

Choose Starlark-rust if you're embedding in Rust for best interoperability; opt for Starlark-go if you're in a Go ecosystem. Starlark-rust offers better Rust integration but has less stable APIs compared to the more mature Go version.

Question 3

Does starlark-rust work with VS Code?

Accepted Answer

Yes, it supports IDE integration via LSP, and there's a VS Code extension mentioned in the README, but for custom bindings, you may need to build your own language server.

Question 4

How can I debug Starlark scripts in Rust?

Accepted Answer

Leverage the Debug Adapter Protocol (DAP) support in the library to set up debugging; however, this requires integrating the debugger with your custom binary for full functionality.

Question 5

Is the starlark-rust API stable for production?

Accepted Answer

No, the project explicitly does not aim for API stability between releases, preferring rapid iteration, so frequent updates might break compatibility in production environments.

Question 6

How to add custom functions in starlark-rust?

Accepted Answer

Define Rust functions and use the starlark library to expose them as Starlark callables, but you'll likely need to create a custom binary or integration layer, as the standard binary lacks domain-specific bindings.
