Crate partialdebug

Derive Debug for types where not all fields implement Debug.

This relies on specialization and thus requires nightly.

Non Exhaustive

Requires the debug_non_exhaustive feature. Only available for structs with named fields.

#![feature(debug_non_exhaustive)]
use partialdebug::non_exhaustive::PartialDebug;

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

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

Traits

AsDebug

Specialized trait used to distinguish between types that implement Debug and one's that don't.
