class Patch p where Source #

A Patch type represents a kind of change made to a datastructure.

If an instance of Patch is also an instance of Semigroup, it should obey the law that applyAlways (f <> g) == applyAlways f . applyAlways g.

Associated Types

type PatchTarget p :: * Source #

Methods

apply :: p -> PatchTarget p -> Maybe (PatchTarget p) Source #

Apply the patch p a to the value a. If no change is needed, return Nothing.

Apply a Patch; if it does nothing, return the original value

composePatchFunctions :: (Patch p, Semigroup p) => (PatchTarget p -> p) -> (PatchTarget p -> p) -> PatchTarget p -> p Source #

Wrap a Map k (NodeInfo k v) representing patch changes into a PatchMapWithMove k v, without checking any invariants.

Like PatchMapWithMove, but for DMap. Each key carries a NodeInfo which describes how it will be changed by the patch and connects move sources and destinations.

Invariants:

A key should not move to itself.
A move should always be represented with both the destination key (as a From_Move) and the source key (as a ComposeMaybe (Just destination))

patchDMapWithMoveToPatchMapWithMoveWith :: forall k v v' a. (v a -> v') -> PatchDMapWithMove (Const2 k a) v -> PatchMapWithMove k v' Source #

Weaken a PatchDMapWithMove (Const2 k a) v to a PatchMapWithMove k v'. Weaken is in scare quotes because the Const2 has already disabled any dependency in the typing and all points are already a, hence the function to map each value to v' is not higher rank.

const2PatchDMapWithMoveWith :: forall k v v' a. (v -> v' a) -> PatchMapWithMove k v -> PatchDMapWithMove (Const2 k a) v' Source #

Strengthen a PatchMapWithMove k v into a 'PatchDMapWithMove (Const2 k a); that is, turn a non-dependently-typed patch into a dependently typed one but which always has a constant key type represented by Const2. Apply the given function to each v to produce a v' a. Completemented by patchDMapWithMoveToPatchMapWithMoveWith
