_Generating the C header:_
Install [cbindgen](https://github.com/eqrion/cbindgen/):
```sh
cargo install cbindgen
```
From the root directory, generate the header file:
```sh
cbindgen --config include/cbindgen.toml --output include/libaries_askar.h
```
Note that a few types are currently defined manually, such as `ByteBuffer`, because of limitations in the binding generator.
