<p>
Values in Gleam are not nullable, so the
<a href="https://hexdocs.pm/gleam_stdlib/gleam/option.html"
><code>gleam/option</code></a
>
standard library module defines Gleam's <code>Option</code> type, which can be
used to represent a value that is either present or absent.
</p>
<p>
The option type is very similar to the result type, but it does not have an
error value. Some languages have functions return an option when there is no
extra error detail to give, but Gleam always uses result. This makes all
fallible functions consistent and removes any boilerplate that would be
required when mixing functions that use each type.
