## Installation
|
||||
|
||||
1. Add this repo as a submodule:
|
||||
```bash
|
||||
git submodule add https://git.berlin.ccc.de/servicepoint/servicepoint-binding-c.git
|
||||
git commit -m "add servicepoint-binding-c submodule"
|
||||
```
|
||||
2. Add a build step for the servicepoint library. If you use make, this could look something like this:
|
||||
```
|
||||
dependencies: FORCE
|
||||
cargo build --manifest-path=servicepoint-binding-c/Cargo.toml --release
|
||||
FORCE: ;
|
||||
```
|
||||
3. Link against the library. If you are on linux and linking statically:
|
||||
```

```bash

git submodule add https://git.berlin.ccc.de/servicepoint/servicepoint-binding-c.git

git commit -m "add servicepoint-binding-c submodule"

# add target to build rust library - cargo will check for dependency changes

cargo build --manifest-path=servicepoint-binding-c/Cargo.toml --release

You have the choice of linking statically (recommended) or dynamically.
|
||||
|
||||
- The C example shows how to link statically against the `staticlib` variant.
|
||||
- When linked dynamically, you have to provide the `cdylib` at runtime in the _same_ version, as there are no API/ABI

When linked dynamically, you have to provide the `cdylib` at runtime in the _same_ version, as there are no API/ABI

guarantees yet.
|

The Makefile in the example directory contains a bunch of additional compiler flags you might want to add depending on your use case.

available [online](https://docs.rs/servicepoint_binding_c/latest/servicepoint_binding_c/)
|

|

## Safety
|
||||
|
||||
Functions expect that C code honors NonNull annotations.
|
||||
|
||||
Any created instances have to be freed in some way.
|
||||
Pointers to those instances cannot be used anymore after that.
|
||||
|
||||
Instances cannot be shared between threads and need to be locked in the using code.
|
||||
|
||||
Enum values have to be used as-is. Do not pass values that are not part of the enum.
|
||||
|
||||
UTF-8 or UTF-32 encoding has to be used properly.
|
||||
|
||||
Brightness values provided as u8 parameters must be in range.
|
||||
