| [section:binary Binary] |
| |
| This module includes different parsers for parsing binary data in |
| various __endianness__. It includes parsers for default (native), |
| little, and big endian binary input. |

| |
| Binary native endian parsers are designed to parse binary byte streams |
| that are laid out in the native __endianness__ of the target |
| architecture. |
