 * Retrieves the fields metadata from a class targetClass.

 * @returns {Record<string, ({ name: string } & Field)>} An object mapping property names to their corresponding metadata, which includes the type and other options.
 * @example
 * ```typescript
 * class MyClass {

 * }
 * const fields = getFieldsFromClass(MyClass);
 * console.log(fields); // Output: { myField: { name: 'myField', type: 'string' } }
