Brave overhauled its Rust adblock engine with FlatBuffers, cutting memory 75%

Both handle that just fine. Go does this via cgo, and has for over a decade.

You do still need to write the interfacing code, but that's true for all languages.

Then by that argument Rust also supports dynamic linking. Actually it’s even better because that approach sacrifices less performance (if done well) than cgo inherently implies.

Well, Rust does support dynamic linking. It just doesn’t (yet) offer a stable ABI. So you need to either use C FFI over the dynamic linking bridge, or make sure all linked libraries are compiled with the same version of the rust compiler.

It was built to do that, yes
