FFI & Language Interop Standards FAQs

Question 1

Which language integrations are specifically covered?

Accepted Answer

While the core principles apply to any C-compatible FFI, it provides detailed implementation examples for Go and the modern Java Panama (FFM) API.

Question 2

How does this skill handle complex Rust types?

Accepted Answer

It advocates for the 'Handle Pattern,' where raw Rust types are wrapped in opaque pointers (void*) to hide internal implementation details while providing safe access through designated C functions.

Question 3

Why are 'SAFETY' comments required in this standard?

Accepted Answer

Since FFI involves unsafe blocks, the skill mandates SAFETY comments to document the specific invariants (non-null, alignment, ownership) that make a particular unsafe operation valid.

Question 4

What is the primary goal of this Claude Code skill?

Accepted Answer

The skill establishes a formal contract for Foreign Function Interfaces (FFI) to ensure that memory ownership and lifetimes are explicitly managed when passing data between Rust and other languages.

Question 5

Does it support automatic header generation?

Accepted Answer

Yes, the skill includes specific configuration standards and CLI commands for using cbindgen to automatically create synchronized C headers from your Rust source code.
