# cdefines
Turn `#define` C codes into Rust constants.
## How to use:
Add to code:
```rust
extern crate cdefines;
#[cdefines::preprocessor]
const IOCTL: &str =
"#define TCGETS 0x5401
#define TCSETS 0x5402
#define TCSETSW 0x5403
#define TCSETSF 0x5404";
```
It gets translated to:
```rust
const IOCTL_TCGETS: usize = 0x5401;
// ...
enum IOCTL {
TCGETS = 0x5401,
// ...
}
```
## What is supported
1. Plain integers(hex, oct, bin, dec) e.g. `#define A 0x1234`.
2. Simple define cascading e.g. `#define A 123` and then `#define B A`.
