📝 Walkthrough

Walkthrough

The native vllm.cpp source advances to ABI 17. Rust bindings expose new completion, transcription, embedding, video, muxing, and server APIs. Tests validate layouts, symbols, ABI metadata, and checked model loading.

Changes

ABI 17 integration

Layer / File(s)	Summary
Native ABI and FFI contract .github/workflows/platforms.yml, vllm-cpp-sys/src/bindings.rs, vllm-cpp-sys/vllm.cpp, vllm-cpp-sys/README.md, vllm-cpp-sys/THIRD_PARTY.md, vllm-cpp-sys/src/lib.rs	The native pin advances to v0.0.2. The bindings target ABI 17 and add completion, transcription, embedding, video, muxing, and server declarations.
FFI layout and symbol conformance vllm-cpp-sys/tests/layout.c, vllm-cpp-sys/tests/layout.rs, vllm-cpp-sys/tests/symbols.rs, Justfile	Tests validate new layouts, field offsets, status values, callback types, 35 exported symbols, server behavior, and ABI 17 smoke tests.
Checked ABI loading vllm-cpp/src/engine.rs, vllm-cpp/src/lib.rs, vllm-cpp/tests/safe_api.rs	Engine loading checks ABI compatibility before calling the native model-parameter default function. Unit and safe API tests validate ABI 17 and the v0.0.2 version prefix.
