Trait delta_inc::Transformer

pub trait Transformer {
    type Delta;

    fn transform_into(&self, d: &Self::Delta) -> Self;
}

A trait describing something which can be transformed by applying a delta. For example, an array [0,1,2] can be transformed into another [3,1,2] by applying a delta which assigns element 0 to 3. This trait describes the functional case, where the receiver is not modified.

Required Associated Types

type Delta

Required Methods

fn transform_into(&self, d: &Self::Delta) -> Self

Apply a given delta to this transformable item, yielding a potentially updated version of this item.

Implementors

impl<T: Transformable + Clone> Transformer for T

Provides a default trait implementation for every type which is transformable. This first clones the item, and then transforms it in place.

type Delta = <T as Transformable>::Delta
