fastdiff is a Python library (current version 0.3.0) that offers a fast, native implementation of a diff algorithm, including a pure Python fallback. It re-implements the core functionality of Python's built-in `difflib` by leveraging Rust compiled to WebAssembly, which can lead to significant performance improvements for string comparisons. The project has an infrequent release cadence, with its last update in May 2021.
pip install fastdiffVerified import paths — ran on the pinned version, not inferred.
This example demonstrates how to import the `compare` function and use it to find the differences between two multi-line strings. The `compare` function returns an iterator of diff operations similar to `difflib`.
Review the project's GitHub for recent activity or explicit stability guarantees if using in a production environment.
Consider benchmarking your specific use case to confirm native performance is active. Ensure your environment is compatible with `wasmer` and WebAssembly execution.
Evaluate if the current feature set and stability meet your needs, as future development may be limited.
pip install fastdiff
Ensure the Rust toolchain and necessary C/C++ build tools are installed for your OS (e.g., Visual C++ Build Tools on Windows), then reinstall fastdiff.
Pass valid string or sequence arguments to 'fastdiff.diff', for example: fastdiff.diff('string1', 'string2')No dependency data recorded yet.
