View Source Funx.Monad.Identity (funx v0.1.7)

The Funx.Monad.Identity module represents the identity monad, where values are simply wrapped in a structure and operations are applied directly to those values.

This module implements the following protocols:

  • Funx.Monad: Implements the bind/2, map/2, and ap/2 functions for monadic operations.
  • Funx.Eq: Defines equality checks for Identity values.
  • Funx.Ord: Defines ordering logic for Identity values.
  • String.Chars: Converts an Identity value into a string representation.
