Cross-compiling Rust for ARM64 targets requires configuring the correct target triple and using tools like rustup, cross, or cargo-zigbuild to manage dependencies and build the binary for the desired architecture.

Building static Rust binaries with musl involves configuring .cargo/config.toml to specify the musl target triple, enabling hermetic builds that run across diverse operating systems without external library dependencies.

cargo-zigbuild facilitates Rust cross-compilation by handling target setup, supporting the generation of WebAssembly modules and building binaries for embedded systems across diverse hardware architectures.

Configuring .cargo/config.toml is necessary to define linker settings and target triples, ensuring hermetic builds correctly map dependencies when cross-compiling Rust code for diverse operating systems and hardware architectures.

Yes, rustup manages toolchains and target setups for bare-metal development, allowing you to download the appropriate target triples and cross-compile Rust applications for embedded systems without a host operating system.

While cross simplifies Rust cross-compilation, complex targets may require manual .cargo/config.toml adjustments or cargo-zigbuild to resolve target triple configurations and ensure hermetic builds for embedded systems.
