Rule Forms Overview

TypeGuard rules are JSON-expressible structures. The core forms are:

• String rules: "string", "uint32", "@MyType(1,2)", "==hello"
• Literal rules: 123, true, false, null
• Object rules: { "name": "string", "age?": "uint8" }
• Array modifier rules: ["$.array", 3, "string"]
• Composite rules: ["$.or", "string", "int"]
