A library to decode and encode headers for the gzip format. The library also contains a reader absctraction over a CRC checksum hasher.
A file in the gzip format contains a gzip header, a number of compressed data blocks in the DEFLATE format, and ends with the CRC32-checksum (in the IEEE format) and number of bytes (modulo
2^32) of the uncompressed data.
The gzip header is purely a set of metadata, and doesn't have any impact on the decoding of the compressed data other than the fact that
DEFLATE-encoded data with a gzip-header is checked using the CRC32 algorithm.
This library is based on the gzip header functionality in the flate2 crate.
