ExOptional

ExOptional provides a (minimal) set of functions to work with "Optional" types.

In Elixir, Optional types are really just two-element tuples. Success Optionals look like

{ :ok, value }

while failed Optionals have some other value for the first element. (ExOptional uses :no by default, but largely doesn't care.)

Currently, failed Optionals will only have a value of nil. In the future, ExOptional may support failed values as well.

Installation

If available in Hex, the package can be installed as:

1. Add ex_optional to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:ex_optional, "~> 0.1.0"}]
end
```

1. Ensure ex_optional is started before your application:

```elixir
def application do
  [applications: [:ex_optional]]
end
```
