Enum Codegen

The ZodTs derive macro also supports enums, generating TypeScript Zod union schemas.

Unit enums

use zod_rs_ts::ZodTs;

#[derive(ZodTs)]
enum Status {
    Active,
    Inactive,
}

fn main() {
    println!("{}", Status::zod_ts());
}

Generated TypeScript:

export const StatusSchema = z.union([
  z.object({ Active: z.null() }),
  z.object({ Inactive: z.null() })
]);

Struct variant enums

#[derive(ZodTs)]
enum Event {
    Click { x: i32, y: i32 },
    Scroll { delta: f64 },
}

fn main() {
    println!("{}", Event::zod_ts());
}

Generated TypeScript:

export const EventSchema = z.union([
  z.object({ Click: z.object({ x: z.number().int(), y: z.number().int() }) }),
  z.object({ Scroll: z.object({ delta: z.number() }) })
]);

Mixed enums

Enums with mixed variant types are fully supported:

#[derive(ZodTs)]
enum ApiResponse {
    Success,
    Data(String),
    Error { code: i32, message: String },
}

The generated schema creates a union with the appropriate structure for each variant.
