Compile Rust CLI tools for multiple platforms using cargo build with release profiles and target triples.
Use cargo build --release with the --target flag to compile your Rust CLI tool for a specific platform, then package the resulting binary.
cargo build --release --target x86_64-unknown-linux-gnu
cargo build --release --target x86_64-pc-windows-msvc
cargo build --release --target x86_64-apple-darwin
Install cross-compilation targets first using rustup target add <target-triple>.
Packaging Rust CLI tools for multiple platforms compiles your code into a standalone program that runs on different operating systems like Windows, Mac, or Linux. It matters because you can distribute one version of your code that works for everyone without them needing to install Rust. Think of it like baking a cake once and freezing it so anyone can eat it later, regardless of what oven they have.
