Summary by CodeRabbit

  • New Features

    • Added a Python package interface for PASETO encryption, decryption, tokens, keys, PASERK, PEM conversion, and errors.
    • Added comprehensive type hints for the public Python API.
    • Added performance benchmarking with comparisons across popular token libraries.
  • Bug Fixes

    • Improved package and extension integration for reliable imports.
  • Tests

    • Expanded automated formatting, linting, type-checking, Rust, and Python integration checks.
    • Release builds now require successful test completion.
  • Documentation

    • Updated usage, architecture, technology, development, and performance guidance.

- Add Performance section with benchmark results against pyseto
- Include comparison table showing speedup metrics for key operations
- Add note about python-paseto library exclusion from benchmarks
- Include instructions to run benchmarks with profiling/benchmark.py
- Update .gitignore to exclude profiling/ directory
- Add pyseto and python-paseto to dev dependencies for benchmarking
- Reorganize product overview to emphasize token types and API patterns
- Add comprehensive PASERK capabilities documentation (key serialization, wrapping, password protection)
- Clarify supported PASETO versions with crypto details per version
- Expand code generation rules with practical do's and don'ts
- Simplify structure guide by removing frontmatter and focusing on architecture patterns
- Consolidate key lengths reference table with Ed25519-specific labeling
- Add PEM loading and footer/assertion support to API surface
- Improve common mistakes section to prevent misuse of public tokens
chore: profiling, test vectors, and Rust core restructure
- ci: add a Test & Lint job (cargo fmt/clippy, cargo test, test-vectors,
  maturin develop, ruff, ty, pytest) and gate the release job on it; the
  workflow previously only built and published wheels
- packaging: switch to a maturin mixed layout so py.typed and the .pyi
  stubs ship in the wheel; rename the pymodule fast_paseto -> _fast_paseto
  and re-export it from the python/fast_paseto package
- deps: move hypothesis from runtime dependencies to the dev group
- tests: replace deprecated PyO3 APIs (prepare_freethreaded_python/with_gil
  -> Python::initialize/attach)
- chore(gitignore): ignore compiled extension artifacts (*.pdb/*.pyd/*.so)
- docs(steering): update stub path references to python/fast_paseto/_fast_paseto.pyi
- clippy: fix expect_fun_call and needless_borrows_for_generic_args in
  test modules (key_generator, key_manager, token_verifier)
- rustdoc: fence the Python REPL examples in bindings.rs as `text` so
  rustdoc no longer compiles them as Rust doctests (fixes 4 failing doctests
  under `cargo test`)
- style: run cargo fmt across the crate; the feature-gated test-vector
  suites were previously unformatted and the new CI enforces
  `cargo fmt --all -- --check`
Newer Rust toolchains reject the ambiguous_glob_imported_traits lint where
both super::* and proptest::prelude::* bring RngCore into scope. Import
rand::RngCore explicitly in the test module so .fill_bytes resolves.

Review Change Stack

📝 Walkthrough

Walkthrough

The change packages the Rust extension as _fast_paseto, adds complete Python exports and type stubs, expands CI validation, adds comparative benchmarks, updates repository metadata and documentation, and reformats Rust implementation and test-vector code without changing cryptographic behavior.

Changes

Package and validation workflow

Layer / File(s) Summary
Python package API and extension wiring
pyproject.toml, python/fast_paseto/*, src/lib.rs
The package now re-exports the Rust API through _fast_paseto. Complete type stubs describe token, cryptographic, PASERK, wrapping, password, and PEM APIs.
Repository metadata and CI workflow
.gitattributes, .gitignore, .github/workflows/CI.yml, .kiro/steering/*
Repository file handling, generated-artifact exclusions, project guidance, and CI test and release dependencies are updated.
Comparative benchmark workflow
profiling/benchmark.py, README.md, pyproject.toml
A benchmark harness compares supported PASETO libraries, uses isolated environments where required, renders timing results, and supports JSON output.
Rust compatibility and formatting updates
src/bindings.rs, src/key_generator.rs, src/key_manager.rs, src/lib.rs, src/test_vectors.rs, src/token_generator.rs, src/token_verifier.rs, tests/rust/property_tests.rs
Rust documentation, imports, PyO3 test APIs, fixed-size array arguments, and formatting are updated without changing runtime behavior.
Versioned test-vector updates
tests/rust/test_vector_property_tests.rs, tests/rust/v2_vectors.rs, tests/rust/v3_vectors.rs, tests/rust/v4_vectors.rs
Test-vector code is reformatted. Optional footers and implicit assertions use explicit None and Some values while preserving test expectations.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 83be2

The PR updates the Python API, token-version declarations, developer commands, publishing workflow, and benchmark output. At the current head, the public API can fail at runtime and advertise unsupported compatibility, while CI and documentation changes can mislead maintainers or affect publishing behavior. The PR is not merge-ready until these concrete issues are corrected or explicitly accepted.

on actions/checkout@v4, and disable caching for tag refs on both
Swatinem/rust-cache@v2 and astral-sh/setup-uv@v5 using the workflow’s non-tag
condition. Preserve caching for non-tag runs.

In @.kiro/steering/tech.md:
- Around line 47-50: Update the setup command block in tech.md to identify the
Windows-specific activation command and add the POSIX activation command using
.venv/bin/activate, while retaining the existing Windows command for Windows
users.
- Line 66: Update the Full Checks command in the documented validation flow to
run cargo test with the test-vectors feature enabled, ensuring the official
vector suites are included.

In `@python/fast_paseto/__init__.pyi`:
- Around line 7-17: Remove the Serializer and Deserializer re-exports from the
fast_paseto package stub’s _fast_paseto import list so type checking matches the
runtime package exports; leave them internal to _fast_paseto.pyi unless they are
defined and exported through a Python module.

In `@python/fast_paseto/_fast_paseto.pyi`:
- Around line 13-41: Update the stub inheritance for PasetoCryptoError,
PasetoExpiredError, and PasetoNotYetValidError to derive directly from
PasetoError, matching the Rust runtime hierarchy; leave PasetoKeyError
inheriting from PasetoValidationError.
- Around line 196-198: Remove the unsupported v3 claims from the Python-facing
documentation: update python/fast_paseto/_fast_paseto.pyi lines 196-198 and the
corresponding encode/decode and Paseto method version descriptions to omit v3,

  • Lines 32 and 34: Swatinem/rust-cache@v2 and astral-sh/setup-uv@v5 enable caching by default. This workflow also runs on tag refs and publishes to PyPI, so restrict caching to non-tag runs.

Include the feature-gated vector tests in the full-check command.

Line 66 runs cargo test without --features test-vectors, so it skips the official vector suites documented at Lines 58-62. A successful “Full Checks” run can therefore miss regressions in those tests. Add cargo test --features test-vectors or state that the command is not exhaustive.

Remove the invalid Serializer and Deserializer re-exports.

fast_paseto.__init__.py imports neither name, and _fast_paseto does not register them. The stub still exposes both names, so from fast_paseto import Serializer can pass type checking but raise ImportError at runtime. Keep these protocols internal to _fast_paseto.pyi or define and export them from a Python module.

Align the exception hierarchy with the Rust bindings.

PasetoCryptoError, PasetoExpiredError, and PasetoNotYetValidError inherit directly from PasetoErrorPy at runtime, not from PasetoValidationError. Update the stub so except PasetoValidationError does not falsely appear to catch these exceptions.

Align documented v3 support with the shipped Python binding.

The Python binding currently routes only v4 and v2 encode/decode combinations; unsupported combinations return PasetoValidationError. However, the Python stubs and steering documentation advertise v3 support, so callers using the documented API can fail at runtime.

Either add the v3 arms to src/bindings.rs, or remove/mark v3 as unavailable in python/fast_paseto/_fast_paseto.pyi and .kiro/steering/product.md until the binding exposes it.

Swatinem/rust-cache@v2 and astral-sh/setup-uv@v5 using the workflow’s non-tag
condition. Preserve caching for non-tag runs.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Show relative-speed columns only when the baseline is available.

If fast-paseto cannot load and other libraries succeed, these conditions add comparison columns with only n/a values. Require an available baseline in both locations.

Proposed fix
-    if baseline is not None and len(names) > 1:
+    if baseline is not None and not baseline.get("unavailable") and len(names) > 1:
         header += [f"{n} vs {BASELINE}" for n in names if n != BASELINE]
...
-        if baseline is not None and len(names) > 1:
+        if baseline is not None and not baseline.get("unavailable") and len(names) > 1:
