Rust's multiple entry points pattern enables unified codebase deployment across heterogeneous execution contexts (CLI, web services, WASM) while maintaining memory safety guarantees and type consistency. Implementation leverages Cargo's binary target specification to encapsulate core logic in library crates, with interface-specific code isolated in discrete entry points. The development workflow prioritizes CLI-first iteration for rapid feedback loops before expanding to stateless service endpoints that benefit from Rust's ownership model. This approach yields compile-time optimization advantages including architecture-specific binary tuning, reduced memory footprint through shared components, and elimination of environment disparity issues in CI/CD pipelines. The pattern fundamentally shifts from runtime-interpreted prototyping to compiled systems with unified error handling and data serialization across all deployment targets.
