ry 0.0.89

ry == rust | python

ry

python bindings for rust crates ~ ry == rust | python

DOCS: ryo3.dev (WIP)

API: ryo3.dev/api

This is a work in progress ~ feedback and PRs are welcome.

Highlights

• Async/Blocking http-clients: Built on reqwest, with a fetch-like API. Supports streaming, zero-copy IO (via the buffer protocol), timeouts, redirect-following, and native JSON (de)serialization.
• WebSocket client: Built on tokio-websockets and styled after jawascript's WebSocket API.
• jiff based datetime library: comprehensive datetime library based on jiff (pydantic-compatible).
• Async file I/O: AsyncFile API similar to aiofiles and anyio's async-file api.
• (de)compression: (de)compression support for zstd, brotli, gzip, and bzip2.
• hashing: aws-lc-rs, fnv, and twox-hash (aka xxhash)
• Ergonomic: APIs designed to be ergonomic and pythonic and familiar to both python and rust users.
• Type Annotated: All public APIs are (painstakingly) type annotated and checked.
• Performant: Speed without the words "blazingly fast." [^1]
• Pydantic Integration: ry data types (mostly) work good w/ pydantic.
• Not slop: Artisanal, hand-crafted, grassfed, fair-trade, small-batch software.
• No emojis
• MANY crate bindings see below.

Install

pip install ry
uv add ry
uv pip install ry

# check install
python -m ry
# run & check install w/ uv
uv run --with ry python -m ry

Quickstart

Bop around the ./examples to see some of what ry can do.

Or to play with ry in a repl, run the following:

# repl w/ ipython
uv run --with ry,ipython python -m ry.dev
# repl w/o ipython
uv run --with ry python -m ry.dev

What?

• ry -- the python package
• ryo3-* -- the rust crates that are used by ry and possibly your own pyo3-based python package

Who?

• jessekrubin [e-mail]
• possibly you!?

FAQ

(aka: questions that I have been asking myself)

• Q: Why?
  • A: I (jesse) needed several hashing functions for python and then kept adding things as I needed them
• Q: Does this have anything to do with the (excellent) package manager rye?
  • A: short answer: no. long answer: no, it does not.
• Q: Why is the repo split into ry and ryo3?
  • A: ry is the python package, ryo3 is a rust crate setup to let you "register" functions you may want if you were writing your own pyo3-python bindings library; maybe someday the ryo3::libs module will be split up into separate packages
