Blocking API

Make synchronous LLM calls without async runtime

Call LLMs synchronously from any Rust code — no async runtime required, no await syntax, no tokio dependency to manage.

Edition

Community — runs on the OSS / Community SDK edition.

What this demonstrates

Difficulty: Starter 🟢 · LLM

• Summary: Synchronous blocking API for simpler use cases
• Scenario: Make synchronous LLM calls without async runtime
• tech_tags in manifest: LLM — example id blocking-api in conformance/examples_manifest.json.

Prerequisites

• SDK: Use an installed SDK tree (NXUSKIT_SDK_DIR, NXUSKIT_LIB_PATH as needed); test-examples.sh resolves Go/Rust/Python deps from that tree only — see README.md, scripts/setup-sdk.sh, and scripts/test-examples.sh.
• Languages in this example: go, rust (paths under this directory; Python may live under a sibling python/ or shared reference per Language Implementations).
• Models: Set cloud provider API keys and/or run Ollama locally when you execute the Run steps (interactive flags like --help / --verbose are documented below).
