// The hierarchy of Soong modules to produce a vmbase-based binary is

// 0. rlibs may be used to provide high-level code (see "vmbase_rlib_defaults");
// 1. rust_ffi_static packages low-level Rust code and any rlib into a static
//    library (see "vmbase_ffi_defaults") that cc_binary supports;
// 2. cc_library_static may be used for extra C code (see "vmbase_cc_defaults");
// 3. cc_binary produces an ELF from the (single) Rust-wrapping static library,
//    optional extra C libraries, and linker script (see "vmbase_elf_defaults");
// 4. raw_binary strips the ELF into an image that can be loaded to memory;

// Used by intermediate rust_library_rlib for vmbase-based binaries.
