Documentation

data PatchOrReplacement p Source #

Either a patch or a replacement value.

A good patch type will describe small changes very efficiently, but that often comes at the cost of describing large change rather inefficiently. PatchOrReplacement can be used as an escape hatch: when the change as a patch would be too big, just provide a new value to replace the old one with instead.

Since: 0.0.6
