import { type Schema } from "https://deno.land/x/scaffold@0.3.0/src/deps/types.ts";
Create a deep version of another object type where property values are recursively replaced into a given value type.
Use-cases:
- Form validation: Define how each field should be validated.
- Form settings: Define configuration for input fields.
- Parsing: Define types that specify special behavior for specific fields.
