Pure Python implementation of Google's Snappy compression algorithm.

uv sync

from src import compress, decompress

# Compress data
data = b"Hello, World!" * 100
compressed = compress(data)

# Decompress data
original = decompress(compressed)
assert original == data

• compress(data: bytes) -> bytes: Compress data using Snappy
• decompress(data: bytes) -> bytes: Decompress Snappy-compressed data

• max_compressed_length(size: int) -> int: Maximum possible compressed size
• get_uncompressed_length(data: bytes) -> int: Read uncompressed length from header
• is_valid_compressed_data(data: bytes) -> bool: Quick validation check

• SnappyDecompressionError: Raised when decompression fails
