Typed

Description

Typed is a dry-types + dry-struct alternative. It provides a similar API in order to ease migration. Compared to dry-struct, Typed has an improved support of "nullable" and "missable" fields:

Typed::String.nullable : accepts a String, or Nil.
Typed::String.missable : accepts a String, or no value at all (represented by Typed::Undefined).
Typed::String.nullable.missable : accepts a String, Nil, or no value at all (represented by Typed::Undefined). This behavior is difficult to obtain with dry-struct.

Typed only targets the use-case of converting controller parameters into Ruby objects with proper type checks and coercions.
