# to_debug

This crate exports the [`ToDebug`]  trait, which is an alternative to

[`ToString`] that uses [`Debug`] instead of [`Display`].

This can be useful for writing doctests, as it allows you to inspect

the values of private fields:

```rust

mod private {

    #[derive(Debug)]

    pub struct Person { name: String, age: u16 }

    // constructor boilerplate...

}

let p = private::Person::new("Joseph", 20);

// assert_eq!(p.name, "Joseph"); // This would fail since `name` is private.

assert_eq!(p.to_debug(), r#"Person { name: "Joseph", age: 20 }"#);

```

[`Debug`]: core::fmt::Debug

[`Display`]: core::fmt::Display
