From 72e0f2aae13bf69787cbedbcf729b85feaf160d8 Mon Sep 17 00:00:00 2001 From: masklinn Date: Mon, 15 Jul 2024 21:22:17 +0200 Subject: [PATCH] pyo3 bindings Advantages ========== - Can do the entire loading in one shot in pure rust from a python iterable. - Work using rust semantics. - Really just works. - Only requires a pyi for type declarations (?). Drawbacks ========= - Likely slower than cffi for pypy, but unlikely to be slower than the slog of pure python. - Graal don't work in tox (oracle/graalpython#427). --- .github/workflows/pychecks.yaml | 41 ++++++ .github/workflows/pyo3-wheels.yml | 193 ++++++++++++++++++++++++++++ .github/workflows/rust.yml | 11 +- .gitignore | 2 + Cargo.toml | 2 +- ua-parser-py/Cargo.toml | 14 +++ ua-parser-py/LICENSE | 201 +++++++++++++++++++++++++++++ ua-parser-py/pyproject.toml | 18 +++ ua-parser-py/src/lib.rs | 202 ++++++++++++++++++++++++++++++ ua-parser-py/tests/test_device.py | 53 ++++++++ ua-parser-py/tests/test_os.py | 63 ++++++++++ ua-parser-py/tests/test_ua.py | 64 ++++++++++ ua-parser-py/tox.ini | 29 +++++ ua-parser-py/ua_parser_rs.pyi | 59 +++++++++ 14 files changed, 945 insertions(+), 7 deletions(-) create mode 100644 .github/workflows/pychecks.yaml create mode 100644 .github/workflows/pyo3-wheels.yml create mode 100644 ua-parser-py/Cargo.toml create mode 100644 ua-parser-py/LICENSE create mode 100644 ua-parser-py/pyproject.toml create mode 100644 ua-parser-py/src/lib.rs create mode 100644 ua-parser-py/tests/test_device.py create mode 100644 ua-parser-py/tests/test_os.py create mode 100644 ua-parser-py/tests/test_ua.py create mode 100644 ua-parser-py/tox.ini create mode 100644 ua-parser-py/ua_parser_rs.pyi diff --git a/.github/workflows/pychecks.yaml b/.github/workflows/pychecks.yaml new file mode 100644 index 0000000..e59f6ab --- /dev/null +++ b/.github/workflows/pychecks.yaml @@ -0,0 +1,41 @@ +name: py checks + +on: + pull_request: + push: + branches: + -
