langium-zod / AstTypesLike

Interface: AstTypesLike

Defined in: types.ts:274

Duck-typed representation of the type model returned by Langium's collectAst() function. Holds the full set of interface types and union/datatype-rule types that the extractor analyses to produce ZodTypeDescriptor records.

Using this interface rather than Langium's concrete AstTypes class means the extractor and tests can supply plain object literals without importing from Langium's grammar internals.

Remarks

Obtain a real AstTypesLike value by calling Langium's collectAst(grammar) and casting the result: collectAst(grammar) as unknown as AstTypesLike. In tests, construct plain objects conforming to this interface directly.

Example

import type { AstTypesLike } from 'langium-zod';

const astTypes: AstTypesLike = {
  interfaces: [{ name: 'Greeting', properties: [{ name: 'message', type: 'STRING', optional: false }] }],
  unions: []
};
