+ Values in Gleam are not nullable, so the + gleam/option + standard library module defines Gleam's Oction type, which can be + used to represent a value that is either present or absent. +

+ +

+ 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 + failible functions consistent and removes any boilerplate that would be + required when mixing functions that use each type. +
