| Rust Type | Kotlin Type |
|---|---|
String | String |
bool | Boolean |
u8, u16, u32, u64 | UByte, UShort, UInt, ULong |
i8, i16, i32, i64 | Byte, Short, Int, Long |
f32, f64 | Float, Double |
Uuid | String |
DateTime<Utc> | kotlinx.datetime.Instant |

Example
Rust:
#![allow(unused)]
fn main() {
#[derive(TypeWriter)]
#[sync_to(kotlin)]
pub struct User {
pub id: String,
pub email: String,
pub age: Option<u32>,
}
}Generated:
package types
import kotlinx.serialization.SerialName
import kotlinx.serialization.Serializable
@Serializable
data class User(
@SerialName("id") val id: String,
@SerialName("email") val email: String,
@SerialName("age") val age: Int? = null
)
Package Name
Configure the Kotlin package name:
[kotlin]
package_name = "com.example.models"
File Naming
Files use PascalCase by default: UserProfile → UserProfile.kt
[kotlin]
file_style = "snake_case" # user_profile.kt
