marrow - minimalist Arrow interop

Crate info | API docs

marrow allows building and viewing arrow arrays of different implementations using a unified interface. The motivation behind marrow is to allow libraries to target multiple different arrow versions simultaneously.

Development

All important development tasks are packaged in the x.py script. It does not require any external dependencies and can be executed with any recent Python version.

• python x.py precommit: wrapper around format, check, test
• python x.py test: execute the tests
• python x.py check: run linters
• python x.py format: format the source code
• cargo test --all-features execute the tests without the x.py script
