Covers setting up Rust targets with rustup, configuring the linker in .cargo/config, optimizing binary size via Cargo.toml release profile settings (opt-level z, LTO, single codegen unit), and building multi-architecture Docker images using Docker buildx with BUILDPLATFORM and TARGETPLATFORM arguments to dynamically select the correct Rust compilation target per architecture. ## Full article daily.dev links to this article rather than hosting it.
