It works with bytes and burst-type errors (common in storage media like hard drives) rather than bit-level noise. The library offers both a pure-Python implementation and an optional Cython-accelerated version for performance-critical use.\n\nYou initialize a codec with a number of error-correction symbols, then encode data by appending those symbols, and decode by passing potentially corrupted data back to recover the original. The codec can correct up to half as many errors as you have correction symbols, or twice as many erasures if you know which positions are corrupted. It's designed for data-at-rest scenarios (backup, archival, storage) rather than streaming or network transmission.","worth_installing":"Yes. Reedsolo is mature, actively maintained, has no dependencies, and is permissively licensed. Install it if you need to protect stored or transmitted data from burst errors and want a straightforward, well-tested implementation. The pure-Python version is fast enough for most use cases; the optional Cython build is available if you need more speed."},"id":"reedsolo","links":{"html":"https://skillfed.io/packages/reedsolo","md":"https://skillfed.io/packages/reedsolo.md","pypi":"https://pypi.org/project/reedsolo/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2023-01-17","license_spdx":null,"license_treatment":"permissive","name":"reedsolo","python_support":"unspecified","summary":"Pure-Python Reed Solomon encoder/decoder"},"popularity":{"monthly_downloads":2814392,"position":2879,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.7.0"}
