Add the ARM target with rustup and build your project using the --target flag for Raspberry Pi compatibility.
Add the ARM target to your Rust toolchain and specify it during the build to compile for Raspberry Pi or similar devices.
rustup target add armv7-unknown-linux-gnueabihf
cargo build --target armv7-unknown-linux-gnueabihf --release
For 32-bit devices like the original Raspberry Pi or Pi Zero, use armv6-unknown-linux-gnueabihf instead of armv7.
Building Rust for ARM translates your code into instructions that a Raspberry Pi's processor can understand. It's like translating a book from English to Spanish so a Spanish speaker can read it. You do this once to get a file that runs directly on the device.
