## Usage example
([Generated type docs](https://docs.rs/proc-bitfield/latest/proc_bitfield/example/struct.ConvRawExample.html))
```rust
#[derive(ConvRaw)]
pub enum ConvRawExample {
A,
B = 2,
C,
D = -1,
E = 1,
F = -128,
G = 128,
}
```
This will implement:
- `TryFrom<T> for ConvRawExample` for all integer types `T`
- `UnsafeFrom<T> for ConvRawExample` for all integer types `T`
- `From<ConvRawExample> for T` for all integer types `T` that contain all discriminants; in this
case, all signed integer types with `>= 16` bits (`i16`, `i32`, `i64`, `i128`)
