MonadEx v1.1.3 Monoid protocol View Source

Monoids have two principle operations: empty/zero and append.

This protocol doesn’t have an empty function due to the limitations of Elixir protocols. I can implement this functionality using Behaviours, but I haven’t done so yet.

All collections, such as lists and strings, are monoids. Many other types are monoids too.
