class Measured f a => CanInsert f a where Source #

Things that can be inserted.

Minimal complete definition

Nothing

Methods

insertMeasure :: a -> f a -> f a Source #

Delete an element form the associated structure

default insertMeasure :: Semigroup (f a) => a -> f a -> f a Source #

class Measured f a => CanDelete f a where Source #

Things that can be deleted.

Methods

Delete the element from the structure. Returns a Maybe since the structure may be empty after deletion (and that may not be representable by f).
