  • Computed checksum of the uncompressed data does not match the value stored in the archive. Associated value contains the data that were successfully decompressed up to the point where the mismatch was detected.

    • When using BZip2.decompress(data:): The associated value comes from a single BZip2 archive. If the mismatch happens at the final checksum verification, this is usually the entire decompressed output.

    • When using BZip2.multiDecompress(data:): The input may contain several concatenated BZip2 archives. The error is thrown for the current archive that fails the checksum. The associated value contains only the data decompressed for that archive. Results from earlier archives are not included and are not returned once this error is thrown.
