Let's say we have one API written in Rust And API caller written in C/C++ They are compiled into separate .wasm obj files How can we linking these obj files together and form a single .wasm file?

Please ask the author to provide a brief introduction to the underlying technical approach, so we can assess if the technical approach is compatible and would work with Tricorder Starship.

Ideally, we should ask them to contribute to Starship repo directly.
