This crate provides a derive macro to derive Serde's `Serialize` and
`Deserialize` traits in a way that delegates to the underlying repr of a C-like
enum.

```toml
[dependencies]
serde = "1.0"
serde_repr = "0.1"
```

```rust
use serde_repr::{Serialize_repr, Deserialize_repr};

#[derive(Serialize_repr, Deserialize_repr, PartialEq, Debug)]
#[repr(u8)]
enum SmallPrime {
    Two = 2,
    Three = 3,
    Five = 5,
    Seven = 7,
}

fn main() -> serde_json::Result<()> {
    let j = serde_json::to_string(&SmallPrime::Seven)?;
    assert_eq!(j, "7");

    let p: SmallPrime = serde_json::from_str("2")?;
    assert_eq!(p, SmallPrime::Two);

    Ok(())
}
```
