📝 WalkthroughWalkthroughThe change adds a workspace maintainer workflow, native and package validation, CI wiring, Hugging Face token fallback, and request-scoped logits processor registrations with lifecycle tests. ChangesWorkspace automation and runtime validation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This release changes workflow credential handling, build and sanitizer linking, runtime request-state retention, and cancellation testing. At the current head, unresolved issues may leave unnecessary credentials configured, break builds on some platforms, accumulate memory in long-lived engines, or cause intermittent CI failures, so the PR needs explicit owner follow-up or acceptance before merging.

The workflow runs only on manual dispatch. MSRV, ARM64, macOS, Metal, and Vulkan regressions then stay undetected until someone remembers to run it. A weekly
scheduletrigger plus dispatch keeps the coverage without adding pull-request cost.🤖 Prompt for AI Agents

In @.github/workflows/ci.yml:
- Around line 25-26: Add persist-credentials: false to every actions/checkout
step in .github/workflows/ci.yml (lines 25-26 and the five recursive-submodule
checkout steps) and .github/workflows/platforms.yml (lines 23-26 and the four
remaining checkout steps); preserve each step’s existing submodules
configuration.
In `@Justfile`:
- Around line 207-214: Update the shared-library copy step near
bundled_static_lib to explicitly locate a matching libvllm.so artifact before
copying, and emit the recipe’s standard diagnostic when none is found. Preserve
copying all matching shared-library files into $prefix/lib/ without allowing an
unexpanded glob to reach cp.
In `@vllm-cpp-sys/build.rs`:
- Around line 343-356: Update link_sanitizer_runtimes to emit compiler-driver
sanitizer arguments instead of direct asan, ubsan, and tsan library names: emit
one cargo:rustc-link-arg=-fsanitize=... argument containing the requested
sanitizer list, preserving combinations such as address,undefined and allowing
the active compiler to select the appropriate runtime.

- Around line 78-84: Update vllm-cpp/src/engine.rs:78-84 in
retain_logits_processor to remove entries without external owners before
appending the new state, preventing unbounded retention. At
vllm-cpp/src/params.rs:348-359, reuse a single LogitsProcessorState per
SamplingParams logits processor when the native user_data contract permits
shared state; otherwise preserve allocation behavior and rely on engine-side
reclamation.
In `@vllm-cpp/src/hf.rs`:
- Around line 167-173: Update api_builder to resolve HF_TOKEN from the
environment when self.token is None, while preserving the explicit self.token
precedence. Pass the resolved token through ApiBuilder::with_token after
ApiBuilder::from_cache(cache), ensuring environment-based authentication is
available before the API client is built.
In `@vllm-cpp/tests/qwen3.rs`:
- Around line 316-341: Update the cancellation assertion in the test around the
cancellable request to accept either RequestOutcome::Cancelled or
RequestOutcome::Completed, matching the existing
concurrent_request_lifecycle_stress behavior, while retaining the cancellation
and completion-state checks.

Clang AddressSanitizer compiler-rt runtime library names Linux macOS -fsanitize linker driver official documentation💡 Result:
The Clang AddressSanitizer (ASan) runtime library files, provided by the compiler-rt project, follow a naming convention that typically takes the form libclang_rt.asan.{a,so,dylib}, depending on the target operating system and whether static or dynamic linking is used [1][2][3]. On Linux (and other ELF-based platforms), the ASan runtime library is generally named libclang_rt.asan.so for shared builds or libclang_rt.asan.a for static builds [1][4]. Starting with LLVM 15.0.0, the default location within the Clang resource directory structure is $resource_dir/lib/$triple/libclang_rt.*.{a,so} [1]. In older versions, or when LLVM_ENABLE_PER_TARGET_RUNTIME_DIR is disabled, the naming convention typically included the architecture suffix, such as libclang_rt.asan-$arch.{a,so} [1]. On macOS (Darwin), the dynamic runtime library is commonly named libclang_rt.asan_{platform}_dynamic.dylib (e.g., libclang_rt.asan_osx_dynamic.dylib) [2][5]. These runtime libraries are intended to be managed by the Clang driver rather than being manually linked by developers [6]. When you compile and link a program using the -fsanitize=address flag, the Clang driver automatically identifies and links the correct version of the library based on the target architecture and operating system [6]. Because these libraries are bundled with the compiler, developers should rely on the Clang compiler driver to handle the link-time search and selection process to ensure compatibility and correct runtime behavior [6][7].

Cargo build script rustc-link-arg documentation applies tests binaries linker arguments💡 Result:
In Cargo build scripts, the
cargo::rustc-link-arg=FLAGinstruction is used to pass custom linker flags [1][2]. According to official Cargo documentation, this instruction applies to all supported "linkable" targets, which explicitly include binaries, tests, benchmarks, examples, and cdylib crates [1][2]. When you usecargo::rustc-link-arg=FLAG, the specified flags are passed to the linker for all of these target types [1]. If you need to target specific categories of artifacts more precisely, Cargo provides more granular instructions: - cargo::rustc-link-arg-tests=FLAG: Applies only to test targets [1][3]. - cargo::rustc-link-arg-bins=FLAG: Applies only to binary targets [1][4]. - cargo::rustc-link-arg-bin=BIN=FLAG: Applies only to a specific binary target by name [1][4]. - cargo::rustc-link-arg-examples=FLAG: Applies only to example targets [1]. - cargo::rustc-link-arg-benches=FLAG: Applies only to benchmark targets [1]. - cargo::rustc-link-arg-cdylib=FLAG: Applies only to cdylib crates [1]. It is important to note that these instructions, specificallycargo::rustc-link-arg-tests=FLAG, are often associated with integration tests (targets in thetests/directory) [5]. Some users have reported that these flags may not automatically apply to unit tests defined within the crate's modules (e.g., insidesrc/), in which case the generalcargo::rustc-link-arg=FLAGis sometimes used as a workaround to capture those binaries [5]. Additionally, usage of these flags is highly platform-specific, as they depend on the underlying linker (e.g.,link.exeon MSVC or other linkers on Unix-like systems) [1][6].Citations:

MarshaledSamplingParams::newallocates a newLogitsProcessorStateon everymarshalcall, andretain_logits_processorappends each one to a vector that is only cleared when the engine drops. Memory therefore grows in proportion to the number of requests that use a logits processor.

hf-hub 0.5 ApiBuilder from_cache default token HF_TOKEN💡 Result:
The
hf-hublibrary (the Rust crate) and thehuggingface_hublibrary (the Python library) are distinct projects with different APIs, though they share common naming conventions and Hugging Face infrastructure concepts [1][2]. Regarding your query aboutApiBuilder::from_cacheand theHF_TOKENenvironment variable in thehf-hubRust crate: 1. ApiBuilder::from_cache: This method is used in the Rusthf-hubcrate to initialize anApiBuilderwith a specificCacheinstance [1][3][4]. It allows for custom configuration of the cache directory [1][5]. 2. Authentication and HF_TOKEN: In thehuggingface_hub(Python) ecosystem,HF_TOKENis the standard environment variable for authentication and takes priority over locally cached tokens [6][2]. In the Rusthf-hubcrate, authentication behavior is handled during the construction of theApiinstance [7]. While the crate manages tokens from a cache file (typically located at~/.cache/huggingface/token) [7][8], standard usage involves building anApiinstance which automatically looks for these credentials [1][7]. If you are working with the Python libraryhuggingface_hub, authentication is handled automatically by checking theHF_TOKENenvironment variable first, followed by the local cache [6][2]. You do not need anApiBuilderto use this; it is the default behavior forHfApiand all root-level API methods [9][10][2]. If you are developing in Rust usinghf-hub, ensure you are using the latest version of the crate, as handling of environment variables (likeHF_HOMEandHF_ENDPOINT) has evolved in recent releases to require explicit opt-in (e.g., viaApiBuilder::from_env()) [3].Citations:

github huggingface hf-hub 0.5.0 src/api/sync.rs ApiBuilder from_cache with_token token file HF_TOKEN💡 Result:
In hf-hub 0.5.0, the ApiBuilder in src/api/sync.rs uses the from_cache method to initialize a builder with a specific Cache instance [1][2][3]. When from_cache(cache) is called, it internally attempts to load a token by invoking cache.token [1][4]. This method looks for a token file at the path derived from the cache directory (typically ~/.cache/huggingface/token) [5][4]. Regarding the interaction between ApiBuilder, tokens, and the HF_TOKEN environment variable: 1. Token Resolution: The library resolves authentication tokens in a specific order: - Explicitly via ApiBuilder::with_token(Some(token)) [1]. - Via the HF_TOKEN environment variable [6][7]. - From a token file at the path specified by HF_TOKEN_PATH [6][7]. - From the default token file at ~/.cache/huggingface/token [6][7]. 2. from_cache and with_token: The ApiBuilder::from_cache(cache) function automatically populates the builder's token field by calling cache.token [1][5]. If you subsequently call.with_token(Some(my_token)) on that builder, it will override the token that was automatically loaded from the cache file [1][3]. 3. Token File: The file referred to as "token" is the Hugging Face CLI authentication token file [4]. If this file does not exist, cache.token simply returns None, and the API proceeds without authentication unless a token is provided via other means like with_token or the HF_TOKEN environment variable [1][5][4]. You can disable this implicit token loading by setting the environment variable HF_HUB_DISABLE_IMPLICIT_TOKEN to a non-empty value [6][7].

docs.rs hf-hub 0.5.0 ApiBuilder from_cache from_env token💡 Result:
In hf-hub version 0.5.0, the ApiBuilder struct is used to configure and instantiate the API client for interacting with the Hugging Face Hub [1]. ApiBuilder::from_cache The from_cache method is used to construct an ApiBuilder based on the local Hugging Face cache configuration [1]. Internally, it initializes a Cache object, which determines the cache directory based on the HF_HOME environment variable (if set) or defaults to ~/.cache/huggingface/hub [2][3]. It also attempts to locate and load the authentication token from the corresponding token file (typically located at ~/.cache/huggingface/token) [2][3]. ApiBuilder::from_env While documentation and usage for ApiBuilder::from_env vary across crate versions, it is designed to configure the API client by respecting standard environment variables such as HF_HOME (for cache location) [4]. In later versions of the library, it is often preferred to ensure proper configuration of the endpoint and cache paths [4]. Token Management The hf-hub crate handles authentication by looking for a token file [2]. The Cache struct provides a token method that checks for the existence of a token file in the expected directory [2]. If the file exists and contains content, it is loaded; otherwise, the method returns None [2]. Users are generally expected to set up this token via the official huggingface-cli login command [2]. Note that in some versions of the library, the automatic check for a token file might log information if the file is missing [3]. To build the final API client, one typically configures the builder using these methods and then calls.build to produce the Api instance [1]. Note that API usage, including the availability of specific builder methods, can depend on the features enabled (such as blocking or tokio) in your Cargo.toml [5][6].
