Install the target toolchain with rustup and build your Rust project using the --target flag to compile for a different platform.
Cross-compile Rust projects by installing the target toolchain with rustup and then building with cargo build --target <target-triple>.
rustup target add <target-triple>
cargo build --target <target-triple>
Replace <target-triple> with your specific destination, such as x86_64-unknown-linux-musl or aarch64-unknown-linux-gnu.
Cross-compiling lets you build software on your current computer that runs on a completely different type of device or operating system. Think of it like baking a cake in your kitchen specifically designed to be eaten at a friend's house with different dietary rules. You use the rustup tool to download the specific instructions for that destination, then tell cargo to use those instructions when building your project.
