# libCwtch-rs
Rust bindings for [libCwtch](https://git.openprivacy.ca/cwtch.im/libcwtch-go/)
Example echobot in examples/echobot.rs (`cargo run --example echobot` -- assumes tor is on $PATH)
## Building
### Updating libCwtch and bingings.rs with Bindgen
```sh
cargo install bindgen
```
libCwtch.so version is specified in build.rs. If updating, also download the corresponding libCwtch.h and delete
the 'preamble from import "C"' section as it imports headers required for the C lib to compile
but that we don't want to create rust bindings for (like importing stdlib.h). Then:
```sh
bindgen libCwtch.h -o src/cwtchlib_go/bindings.rs
```
While developing you can use the `LCG_DIR` environment variable to specify the directory containing a local `libCwtch.so`
library to override the default one.
This is useful in cases where you are adding or updating APIs prior to a release.
