What it is

rust-bert is a Rust-native port of Hugging Face's Transformers library that provides ready-to-use NLP pipelines and pre-trained transformer models (BERT, DistilBERT, GPT-2, T5, BART, etc.) for tasks like question answering, named entity recognition, sentiment analysis, translation, summarization, and text generation. It wraps tch-rs (PyTorch bindings) or ONNX Runtime for inference and rust-tokenizers for preprocessing, enabling GPU-accelerated NLP in pure Rust with no Python dependency. Monorepo structured as: src/lib.rs (core library), examples/ (50+ runnable task-specific examples showing sentiment_analysis.rs, question_answering.rs, translation_m2m100.rs), benches/ (7 performance…

Start here

Open these first:

• src/lib.rs — Entry point and public API surface; exposes all pipelines and model interfaces that users depend on.
• Cargo.toml — Defines core dependencies (tch-rs, ort, rust-tokenizers) and feature flags that control model and backend support.
• src/common/mod.rs — Central hub for common utilities, activations, embeddings, and error handling shared across all model implementations.
• src/common/resources/mod.rs — Abstracts model weight loading from remote (HuggingFace) and local sources; critical for reproducible model initialization.
• src/models/bert/bert_model.rs — Reference implementation of the base BERT architecture; patterns here replicate across all other transformer variants…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/guillaume-be/rust-bert.git
cd rust-bert
cargo build --release --features download-libtorch
cargo run --example sentiment_analysis

Daily commands:

For a specific example: cargo run --example question_answering --release. For benchmarks: cargo bench --bench squad_benchmark. For ONNX backend: `cargo run --example onnx-question-answering --features onnx --release…

…shortened for this brief.

Key cautions & unknowns

• Slowing — last commit 4mo ago
• Concentrated ownership — top contributor handles 58% of recent commits
• 1. libtorch binary bloat: default download-libtorch feature pulls ~1-2GB binary; omit for existing installations or use ONNX path. 2. GPU support implicit: CUDA/cuDNN detection happens in tch-rs; CPU-only…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.

Evidence note

Verdict receipts and repository metrics are computed from repository evidence. Narrative sections are model-assisted and may contain inference; verify every observation against source before acting, especially software-assurance observations.
