Rust Multiple Entry Points: Architectural PatternsKey Points Core Concept: Multiple entry points in Rust enable single codebase deployment across CLI, microservices, WebAssembly and GUI contexts * Implementation Path: Initial CLI development → Web API → Lambda/cloud functions * Cargo Integration*: Native support via src/bin directory or explicit binary targets in Cargo.toml

Technical Advantages Memory Safety: Consistent safety guarantees across deployment targets * Type Consistency: Strong typing ensures API contract integrity between interfaces * Async Model: Unified asynchronous execution model across environments * Binary Optimization: Compile-time optimizations yield superior performance vs runtime interpretation * Ownership Model*: No-saved-state philosophy aligns with Lambda execution context

Deployment Architecture Core Logic Isolation: Business logic encapsulated in library crates * Interface Separation: Entry point-specific code segregated from core functionality * Build Pipeline: Single compilation source enables consistent artifact generation * Infrastructure Consistency: Uniform deployment targets eliminate environment-specific bugs * Resource Optimization*: Shared components reduce binary size and memory footprint

Implementation Benefits Iteration Speed: CLI provides immediate feedback loop during core development * Security Posture: Memory safety extends across all deployment targets * API Consistency: JSON payload structures remain identical between CLI and web interfaces * Event Architecture: Natural alignment with event-driven cloud function patterns * Compile-Time Optimizations*: CPU-specific enhancements available at binary generation
