 ### @class
 
-Define a class. Can be used with [`@field`](#field) to define a table structure. Once a class is defined, it can be used as a type for [parameters](#param), [returns](#return), and more. A class can also inherit from a parent class. Marking the class as `(exact)` means fields cannot be injected after the definition.
