typewriter
Cross-Language Type Synchronization SDK for Rust
Define your types once in Rust. Get perfectly matching types in TypeScript, Python, Go, Swift, Kotlin, GraphQL, and JSON Schema — automatically, forever.
Features
- Annotate once → generate everywhere: Add
#[derive(TypeWriter)]to your Rust structs/enums - Zero drift: Types stay in sync automatically on every build
- Multiple languages: TypeScript, Python, Go, Swift, Kotlin, GraphQL, JSON Schema
- Zod schemas: Automatic validation schemas for TypeScript
- CLI tools: Project-wide generation, drift checking, watch mode
Quick Example
#![allow(unused)]
fn main() {
use typebridge::TypeWriter;
use serde::{Serialize, Deserialize};
#[derive(Serialize, Deserialize, TypeWriter)]
#[sync_to(typescript, python, go)]
pub struct User {
pub id: String,
pub email: String,
pub name: String,
pub age: Option<u32>,
}
}This generates:
TypeScript:
export interface User {
id: string;
email: string;
name: string;
age?: number | undefined;
}
Python:
class User(BaseModel):
id: str
email: str
name: str
age: Optional[int] = None
Go:
type User struct {
Id string `json:"id"`
Email string `json:"email"`
Name string `json:"name"`
Age *uint32 `json:"age,omitempty"`
}
