View Source Funx.Macros (funx v0.1.0)
Provides macros for automatically implementing Funx.Eq and Funx.Ord protocols
for a given struct based on a specified field.
These macros simplify the process of defining equality and ordering behaviors for custom structs by leveraging an existing field's comparison operations.
Summary
Functions
Generates an implementation of the Funx.Eq protocol for the given struct,
using the specified field as the basis for equality comparison.
Examples
defmodule Person do
defstruct [:name, :age]
end
require Funx.Macros
Funx.Macros.eq_for(Person, :age)
iex> Eq.eq?(%Person{age: 30}, %Person{age: 30})
true
iex> Eq.eq?(%Person{age: 25}, %Person{age: 30})
falseGenerates an implementation of the Funx.Ord protocol for the given struct,
using the specified field as the basis for ordering comparisons.
Examples
defmodule Person do
defstruct [:name, :age]
end
require Funx.Macros
Funx.Macros.ord_for(Person, :age)
iex> Ord.lt?(%Person{age: 25}, %Person{age: 30})
true
iex> Ord.gt?(%Person{age: 35}, %Person{age: 30})
true
