Serry - the unstructured Serde

NOTE:

Serry's API and data representations are somewhat unstable. They may be subject to breaking changes.

Serde is a great library, but can sometimes be undesirable - it demands you use an abstract but structured view of your data such that it may be serialised into virtually any format.

Serry is different - it is a serialisation and deserialisation library that explicitly does not specify a format for its consumers - it leaves the specifics of serialisation and deserialisation up to each type to implement. The only things Serry does is provide some common facilities and utilities to serialise data.

Usage

Implementing manually

The main traits used in Serry are the SerryRead and SerryWrite traits. As the names suggest

Data representations

All Serry-provided representations attempt to be somewhat parseable by non-Rust programs.

Integers

Integers are represented in little-endian (this may be subject to change, but probably will not).

Vectors (for T)

Vectors begin with a u64 which determines its length. Then, Serry will read n amount of Ts into a vector.

HashMap (for K and V)

HashMaps are internally represented effectively as Vectors of (K, V). This means that you could interpret the encoded data as a list of entries or as a map of keys to values.

Note that Serry makes no guarantee of the order of the elements. If a predictable order is desirable, please use vectors.

Strings

Strings are effectively represented as Vectors of u8. They are encoded as UTF-8. The only difference between using Vec and Strings is that String guarantees a valid UTF-8 string.
