 ## About
 
 Elembic lets you create **custom elements,** which are **reusable document components,** with support for **typechecked fields, show and set rules** (without using any `state` by default), **revoke and reset rules, reference and outline support,** and more. In addition, Elembic lets you create **custom types,** which also support **typechecked fields** but also **custom casting**, and can be used in element fields or by themselves in arbitrary Typst code.

 Not only does Elembic support **using and combining Typst-native types** (e.g. a field can take `e.types.union(int, stroke)` to support integers or strokes), but it also supports **declaring your own custom, nominal types**. They are represented as dictionaries, but **are strongly-typed,** such that a dictionary with the same fields won't cast to your custom type and vice-versa by default (unless you specify otherwise). For example, a data type representing a `person` won't cast to another type `owner` even if they share the same fields.
 
 Custom types optionally support **arbitrary casting from other types.** For example, you may allow automatic casts from integers and floats to your custom type. This is mostly useful when creating "ad-hoc" types for certain elements with fully customized behavior. You can read more in the ["Custom types" chapter](./types/custom-types/.).
