Deku is a declarative binary parser. deku_string is an extension which currently provides utility wrappers for data vectors and unicode strings, which can be prefixed or fixed length. Additionally library provides support for 7-bit encoded integers from .NET.

For example, I often work with binary structures where strings are either length prefixed (with zero character in a buffer) or in fixed size buffer with a zero-ended sting inside.

There’s multiple examples with custom writer and reader functions, which work, but are less convenient to use.

Any additional ideas for utilities are welcome.
