Install the target toolchain with rustup and build your project using the --target flag to cross-compile Rust for different architectures.
To cross-compile Rust for a different target, install the target toolchain with rustup and then build your project using cargo build with the --target flag.
rustup target add <target-triple>
cargo build --release --target <target-triple>
Replace <target-triple> with the specific architecture you need, such as wasm32-unknown-unknown or aarch64-linux-gnu.
Cross-compiling means building your Rust program on your current computer so it can run on a completely different type of device or operating system. You do this by telling the Rust toolchain to download the specific tools needed for that other device and then instructing the build process to create the file in that device's format. It is like baking a cake in your kitchen but using a recipe specifically designed for a different oven so the cake turns out perfectly when you move it there.
