Depending on Rust Code from Chromium C++

Simply add the above target to the deps of some Chromium C++ target.

import("//build/rust/rust_static_library.gni") rust_static_library("my_rust_lib") { crate_root = "lib.rs" sources = [ "lib.rs" ] } # or source_set, static_library etc. component("preexisting_cpp") { deps = [ ":my_rust_lib" ] }

Speaker Notes

We'll see that this relationship only works if the Rust code exposes plain C APIs which can be called from C++, or if we use a C++/Rust interop tool.
