Header diving certainly works well for some C/C++ codebases, but not all I've sadly discovered. The rough analog in Rust might be grepping rustdoc generated documentation, which should at least generally tell you what exists / is publicly exposed. Grepping the full source with extra filters like \bfn\b or \bpub fun\b might be another option. Like C++, you can also (ab)use intellisense to find a lot of them as well. I should hack more on Visual Rust to improve the situation there...
