Instances

A property that can be reverted.

class IsProp p whereSource

Methods

describe :: p -> Desc -> pSource

Sets description.

toProp :: p -> PropertySource

requires :: p -> Property -> pSource

Indicates that the first property can only be satisfied once the second one is.

setAttr :: p -> SetAttrSource

class ActionResult a whereSource

data PrivDataField Source
