FFI (Foreign Function Interface) bindings for ODBC (Open Database Connectivity)
As ffi bindings to C-APIs are low level by nature this library is intended to be the foundation of
other libraries to build on top, rather than to be used directly.
## Design Goals
* Providing declarations of ODBC Symbols compatible to the C-Interface of an ODBC Driver Manager
* Provide correct definition of symbols for Unix and Windows in either 32Bit or 64Bit flavour
* Not to abstract away any power of the underlying API
* Increase type safety where feasible
* As it is as of now unlikely to happen that anyone is writing ODBC 2.0 applications in Rust
therefore deprecated symbols like 'SQLAllocEnv' have been left out intentionally.
## Linking
This library will link against `odbc32.dll` (preinstalled) on Windows systems. On Linux and macOS it links against `libodbc.so` by default. This is typically provided by [unix-odbc](http://www.unixodbc.org/). Using the `--feature iodbc` you can also link against `libiodbc.so`. This may be interesting if you are trying to connect to some older data sources on macOS.
## Installing `unix-odbc`
### Linux
Use your systems packet manager to install `unixodbc-dev`. E.g. on Ubuntu / Debian
```shell
sudo apt install unixodbc-dev
```
### macOS
On Intel based architectures you can install `unix-odbc` using homebrew.
```shell
brew install unixodbc
```
Note for **ARM** based macOS Systems (M1 processors and later):
`cargo build` is not going to pick up `libodbc.so` installed via homebrew due to the fact that homebrew on ARM Mac installs into `/opt/homebrew/Cellar` as opposed to `/usr/local/opt/`.
You find documentation on what directories are searched during build here: .
You can also install unixODBC from source:
1. copy the unixODBC-2.3.9.tar.gz file somewhere you can create files and directories
2. gunzip unixODBC*.tar.gz
3. tar xvf unixODBC*.tar
4. `./configure`
5. `make`
6. `make install`
Thanks to @TBPixel for testing this!
### Windows
As windows does ship with ODBC preinstalled, you are good to go out of the box.
## Current State
Symbols are added to this library as we go along implementing uses cases in higher level APIs. If you miss something please do not hesitate to contribute.
## Documentation
Thanks to the folks of [docs.rs] for building and hosting the [documentation]!
