This is a small release to support Deku 0.20.0 release. The only incompatibility was an introduced descriptive-errors feature which is explicitly propagated at the moment.

The crate started as support decoding and encoding fixed and variable length unicode strings, but quite soon become more than this.

While there’s some ideas to implement, new ideas and improvements are always welcome.

Hey, what's a common usecase for deku and deku_string?

[-] blazebra@programming.dev 3 points 3 weeks ago

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.
