# UN Rust Client - Build and Test
#
# This client has two implementations:
#   - sync/  : Synchronous Rust SDK (blocking reqwest)
#   - async/ : Asynchronous Rust SDK (tokio + async reqwest)
#
# Usage:
#   make              # Build all
#   make test         # Run all 4 test modes
#   make test-cli     # CLI mode only
#   make test-library # Library mode only
#   make test-integration # Integration mode only
#   make test-functional  # Functional mode only
#   make build        # Build binaries
#   make clean        # Remove build artifacts
#
# Dependencies:
#   rustup (https://rustup.rs/)
#   cargo
