# OnionPack

Crate that will unpack your struct for layered architecture.

## Usage

```rust
// This:

#[derive(onionpack::OnionPack)]
#[onion_derive(
  all(Debug),          // Describes what derives will have all structs
  dto(PartialEq, Eq)   // Describes what derives will have `UserDto`
  // Can be appended wtith `scheme` and `entity` if you need derives for them.
)]
struct User {
  name: String,              // No `onion_dist` mean that this field will appear in all structs.
  #[onion_dist(dto, entity)] // Describes where field will appear: `scheme` and/or `dto` and/or `entity`.
  password_hash: String,
  #[onion_dist(none)]        // Doesn't appear in child structs.
  hidden_value: i32,
}

// Generates this:

#[derive(Debug)]
pub struct UserScheme {
  name: String,
}

#[derive(Debug, PartialEq, Eq)]
pub struct UserDto {
  name: String,
  password_hash: String,
}

#[derive(Debug)]
pub struct UserEntity {
  name: String,
  password_hash: String,
}
```
