# `:core:model` (Meshtastic Domain Models)
|
|
|
|
## Overview
|
|
The `:core:model` module is a **Kotlin Multiplatform (KMP)** library containing the domain models and data classes used throughout the application and its API. These models are platform-agnostic and designed to be shared across Android, JVM, and future supported platforms.
|
|
|
|
## Multiplatform Support
|
|
Models in this module use the `CommonParcelable` and `CommonParcelize` abstractions from `:core:common`. This allows them to maintain Android `Parcelable` compatibility (via `@Parcelize`) while residing in `commonMain` and remaining accessible to non-Android targets.
|
|
|
|
## Key Models
|
|
|
|
- **`DataPacket`**: Represents a mesh packet (text, telemetry, etc.).
|
|
- **`NodeInfo`**: Contains detailed information about a node (position, SNR, battery, etc.).
|
|
- **`DeviceHardware`**: Represents supported Meshtastic hardware devices and their capabilities.
|
|
- **`Channel`**: Represents a mesh channel configuration.
|
|
|
|
## Usage
|
|
This module is a core dependency of `core:api` and most feature modules.
|
|
|
|
```kotlin
|
|
// In commonMain
|
|
implementation(projects.core.model)
|
|
```
|
|
|
|
## Structure
|
|
- **`commonMain`**: Contains the majority of domain models and logic.
|
|
- **`androidMain`**: Contains Android-specific utilities and implementations for `expect` declarations.
|
|
- **`androidUnitTest`**: Contains unit tests that require Android-specific features (like `Parcel` testing via Robolectric).
