#[derive(PartialDebug)]

    eyes: usize,
    dna: DNA,
}

assert_eq!(format!("{:?}", Dog::new()), "Dog { legs: 4, eyes: 2, .. }");

Placeholder with Type Info

use partialdebug::placeholder::PartialDebug;

#[derive(PartialDebug)]
struct Dog {
    legs: usize,
    eyes: usize,
    dna: DNA,
}

assert_eq!(format!("{:?}", Dog::new()), "Dog { legs: 4, eyes: 2, dna: DNA }");

Placeholder with Custom Text

use partialdebug::placeholder::PartialDebug;

#[derive(PartialDebug)]
#[debug_placeholder = "Unknown"]
struct Dog {
    legs: usize,
    eyes: usize,
    dna: DNA,
}
