Python
Generates Python Pydantic v2 models.
Type Mappings
| Rust Type | Python Type |
|---|---|
String | str |
bool | bool |
u8, u16, u32, u64, i8, i16, i32, i64 | int |
f32, f64 | float |
Uuid | UUID |
DateTime<Utc> | datetime |
Option<T> | Optional[T] = None |
Vec<T> | list[T] |
HashMap<K, V> | dict[K, V] |
Example
Rust:
#![allow(unused)]
fn main() {
#[derive(TypeWriter)]
#[sync_to(python)]
pub struct User {
pub id: String,
pub email: String,
pub age: Option<u32>,
}
}Generated:
from pydantic import BaseModel
from typing import Optional
class User(BaseModel):
id: str
email: str
age: Optional[int] = None
Dataclass Mode
Use Python dataclasses instead of Pydantic:
[python]
use_dataclass = true
pydantic_v2 = false
from dataclasses import dataclass
from typing import Optional
@dataclass
class User:
id: str
email: str
age: Optional[int] = None
File Naming
Files use snake_case by default: UserProfile → user_profile.py
[python]
file_style = "kebab-case" # user-profile.py
# or
file_style = "PascalCase" # UserProfile.py
