Generating Idiomatic Code Models: Go, Rust & Python

Technical guide on synthesizing strongly-typed Go structs with json tags, Rust Serde models with derive macros, and Python Pydantic BaseModel classes.

Transforming sample API responses into backend models saves hours of boilerplate coding across microservices.

1. Go Structs (with JSON tags)

package models
type UserPayload struct {
    ID        int64    json:"id"
    Username  string   json:"username"
    Email     string   json:"email"
    IsAdmin   bool     json:"is_admin"
    Roles     []string json:"roles"
}

2. Rust Structs (Serde Serialize & Deserialize)

use serde::{Deserialize, Serialize};
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct UserPayload {
    pub id: i64,
    pub username: String,
    pub email: String,
    pub is_admin: bool,
    pub roles: Vec<String>,
}

3. Python (Pydantic v2 BaseModels)

from pydantic import BaseModel, EmailStr
from typing import List
class UserPayload(BaseModel):
    id: int
    username: str
    email: EmailStr
    is_admin: bool
    roles: List[str]
