Struct DecompressReader

Source 
pub struct DecompressReader<R> {
    pub inner: R,
    /* private fields */
}
Expand description

A reader wrapper that decompresses data on the fly using DEFLATE algorithm. Header format:

  • First byte: compression type (00 = compressed, 01 = uncompressed, FF = end)
  • Bytes 1-3: length of compressed data (little-endian)
  • Bytes 4-7: CRC32 checksum of uncompressed data (little-endian)
