### Renet Server and Client Plugin Setup in Rust

Source: https://docs.rs/bevy_renet/latest/src/bevy_renet/lib.rs

Demonstrates the setup for RenetServerPlugin and RenetClientPlugin within a Bevy application. These plugins manage the server and client update loops and event emission, relying on Bevy's App and system scheduling. They are designed to run within the PreUpdate schedule and depend on the existence of RenetServer or RenetClient resources.

```rust
impl Plugin for RenetServerPlugin {
    fn build(&self, app: &mut App) {
        app.init_resource::<Messages<ServerEvent>>();
        app.add_systems(PreUpdate, Self::update_system.run_if(resource_exists::<RenetServer>));
        app.add_systems(
            PreUpdate,
            Self::emit_server_events_system
                .in_set(RenetReceive)
                .run_if(resource_exists::<RenetServer>)
                .after(Self::update_system),
        );
    }
}

impl Plugin for RenetClientPlugin {
    fn build(&self, app: &mut App) {
        app.add_systems(PreUpdate, Self::update_system.run_if(resource_exists::<RenetClient>));
    }
}
```

--------------------------------

### RenetClientPlugin Setup

Source: https://docs.rs/bevy_renet/latest/bevy_renet

```rust
fn build(&self, app: &mut App)
fn ready(&self, _app: &App) -> bool
fn finish(&self, _app: &mut App)
fn cleanup(&self, _app: &mut App)
fn name(&self) -> &str
fn is_unique(&self) -> bool
```

--------------------------------

### Plugin Implementation for NetcodeClientPlugin

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/struct.NetcodeClientPlugin

```rust
impl Plugin for NetcodeClientPlugin {
    fn build(&self, app: &mut App)

```rust
impl Error for NetcodeError
...
fn source(&self) -> Option<&(dyn Error + 'static)>
```

--------------------------------

### Manage Server Transport Configuration and Status in Rust

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/struct.NetcodeServerTransport

Provides functions to retrieve and modify server transport details. This includes getting the server's public address, the maximum number of clients, the current number of connected clients, and client-specific information like user data and addresses.

```rust
pub fn addresses(&self) -> Vec<SocketAddr>

Returns the server public address
```

```rust
pub fn max_clients(&self) -> usize

Returns the maximum number of clients that can be connected.
```

```rust
pub fn set_max_clients(&mut self, max_clients: usize)

Update the maximum numbers of clients that can be connected.
Changing the `max_clients` to a lower value than the current number of connect clients does not disconnect clients. So `NetcodeServerTransport::connected_clients()` can return a higher value than `NetcodeServerTransport::max_clients()`.
```

```rust
pub fn connected_clients(&self) -> usize

Returns current number of clients connected.
```

```rust
pub fn user_data(&self, client_id: u64) -> Option<[u8; 256]>

Returns the user data for client if connected.
```

```rust
pub fn client_addr(&self, client_id: u64) -> Option<SocketAddr>

Returns the client address if connected.
```

#### `impl<T> ToOwned for T` where `T: Clone`

##### `type Owned = T`
The resulting type after obtaining ownership.

##### `fn to_owned(&self) -> T`
Creates owned data from borrowed data, typically by cloning.

### Initialize NetcodeServerTransport in Rust

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/struct.NetcodeServerTransport

Creates a new NetcodeServerTransport instance, which is essential for server-side network communication. It requires server configuration and a UDP socket. Returns a Result containing the transport or an Error.

```rust
pub fn new( server_config: ServerConfig, socket: UdpSocket, ) -> Result<NetcodeServerTransport, Error>
```

--------------------------------

### Client Connection Status Functions

Checks if a client is currently connected.

#### `client_connecting`

##### Description

Checks if a client is in the process of connecting.

#### `client_disconnected`

##### Description

Checks if a client has been disconnected.

#### `client_just_connected`

##### Description

Checks if a client has just connected in the current frame.

#### `client_just_disconnected`

```

--------------------------------

### From/Into: Type Conversions

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/struct.ConnectToken

These implementations provide straightforward type conversions. `From<T> for T` allows creating a type `T` from `T` itself, returning the argument unchanged. `Into<U> for T` calls `U::from(self)`, enabling conversions where a `From` implementation exists.

```rust
fn from(t: T) -> T
```

```rust
fn into(self) -> U
```

    pub current_time: Duration,
    pub max_clients: usize,
    pub protocol_id: u64,
    pub public_addresses: Vec<SocketAddr>,
    pub authentication: ServerAuthentication,
}
```

--------------------------------

### Implement `Equivalent` Trait for Comparison (Rust)

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/enum.NetcodeDisconnectReason

```rust
impl<K> Equivalent<K> for K {
    fn equivalent(&self, key: &K) -> bool {
        self == key
    }
}
```

### Implement TryInto for Type Conversion

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/struct.NetcodeServerPlugin

Implements the `TryInto` trait, allowing types to be converted into another type that implements `TryFrom`. The `try_into` function attempts the conversion and returns a `Result`, encapsulating success or failure with the associated error type.

```rust
impl<T, U> TryInto<U> for T
where
    U: TryFrom<T>,

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

    pub version_info: [u8; 13],
    pub protocol_id: u64,
    pub create_timestamp: u64,
    pub expire_timestamp: u64,
    pub xnonce: [u8; 24],

```

--------------------------------

### Implement `From` Trait for Type Conversion (Rust)

Source: https://docs.rs/bevy_renet/latest/bevy_renet/netcode/enum.NetcodeDisconnectReason

Demonstrates the `From` trait implementation, which allows for converting one type into another. The `from` method takes ownership of the input `t` and returns it unchanged, relying on the specific `From<T> for T` implementation.

```rust
impl<T> From<T> for T {
    fn from(t: T) -> T {
        t
    }
}
```
