Trait delta_inc::PartialTransformer

pub trait PartialTransformer: Sized {
    type Delta;
    type Error;

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

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. Furthermore, this trait allows for the possibility that the transformation may not succeed.

Required Associated Types

type Delta

type Error

Required Methods

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

Apply a given delta to this transformable item, yielded a potentially updated version of this item or an error..

Implementors

impl<T: PartiallyTransformable + Clone> PartialTransformer 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 PartiallyTransformable>::Delta

type Error = <T as PartiallyTransformable>::Error
