customdebugderive

Derive Debug with a custom format per field.

Usage

Here is a showcase of all possible field attributes:

```rust #[macrouse] extern crate customdebug_derive; use std::fmt;

#[derive(CustomDebug)]
struct Foo {
    #[debug(format = "{} things")]
    x: f32,
    #[debug(skip)]
    y: f32,
    #[debug(with = "hex_fmt")]
    z: f32,
}

fn hex_fmt<T: fmt::Debug>(n: &T, f: &mut fmt::Formatter) -> fmt::Result {
    write!(f, "0x{:02X?}", n)
}

```

The resulting debug output would look something like this:

Foo { x: 42 things, z: 0xAB }
