# layer-tl-types

Auto-generated Rust types for all Telegram API Layer 224 constructors, functions, and enums.

2,329 TL definitions generated at build time. Includes binary TL serialization and deserialization via `Serializable` and `Deserializable` traits.

---

## Installation

```toml
[dependencies]
layer-tl-types = "0.4.7"

# With MTProto low-level types (required by layer-mtproto):
layer-tl-types = { version = "0.4.7", features = ["tl-mtproto"] }
```

---

## Generated Structure

```rust
// TL constructors become structs
pub mod types {
    pub struct Message {
        pub id:      i32,
        pub peer_id: enums::Peer,
        pub message: String,
        // optional fields wrapped in Option<>
    }
}

// Abstract TL types become enums
pub mod enums {
    pub enum Message {
        Message(types::Message),
        Service(types::MessageService),
        Empty(types::MessageEmpty),
    }
}

// TL functions become structs implementing RemoteCall
pub mod functions {
    pub mod messages {
        pub struct SendMessage { /* fields */ }
        impl RemoteCall for SendMessage {
            type Return = enums::Updates;
        }
    }
}
```

## Feature Flags

| Feature | Default | Description |
|---|---|---|
| `tl-api` | yes | Telegram API schema (`api.tl`) |
| `tl-mtproto` | no | MTProto internal schema (`mtproto.tl`) |
| `impl-debug` | yes | `#[derive(Debug)]` on all types |
| `impl-from-type` | yes | `From<types::T> for enums::E` |
| `impl-from-enum` | yes | `TryFrom<enums::E> for types::T` |
| `deserializable-functions` | no | `Deserializable` on function types |
| `name-for-id` | no | `name_for_id(u32) -> Option<&'static str>` |
| `impl-serde` | no | `serde::Serialize` / `Deserialize` |

---

## Updating the TL Schema

```bash
cp new-api.tl layer-tl-types/tl/api.tl
cargo build
```

`layer-tl-gen` regenerates all types at compile time via `build.rs`. No manual code changes needed.

---

## Stack position

```
layer-client
└ layer-mtproto
  └ layer-tl-types  <-- here
    └ (build) layer-tl-gen
      └ (build) layer-tl-parser
```
