Trait Loss 

pub trait Loss: Clone + Default {
    // Required methods
    fn zero() -> Self;
    fn total() -> Self;
    fn is_zero(&self) -> bool;
    fn combine(self, other: Self) -> Self;
}

A measure of what didn’t survive a transformation.

Loss forms a monoid: zero() is the identity element, combine is associative, and total() is the absorbing element (annihilator).

Required Methods

fn zero() -> Self

The identity: no loss occurred. combine(zero(), x) == x.

fn total() -> Self

Total loss: the transformation destroyed everything. Acts as an absorbing element under combine.

fn is_zero(&self) -> bool

Whether this loss is zero (lossless).

fn combine(self, other: Self) -> Self

Accumulate two losses. Associative: a.combine(b).combine(c) == a.combine(b.combine(c)).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
