Trait Implementations§

source§

impl Backend for NoBackend

§

type ClientData = ()

The type of data that can be stored in ConnectedClient::set_client_data. This allows state to be stored associated with each connected client.
§

type Error = Infallible

The error type that can be returned from the backend functions. If a backend doesn’t need an error type, Infallible can be used.
source§

fn configure( config: ServerConfiguration<Self> ) -> Result<ServerConfiguration<Self>, BackendError<Self::Error>>

Invoked once before the server is initialized.
source§

fn initialize<'life0, 'life1, 'async_trait>( &'life0 self, server: &'life1 CustomServer<Self> ) -> Pin<Box<dyn Future<Output = Result<(), BackendError<Self::Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Invoked once after initialization during Server::open/CustomServer::open.
source§

fn client_connected<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, client: &'life1 ConnectedClient<Self>, server: &'life2 CustomServer<Self> ) -> Pin<Box<dyn Future<Output = Result<ConnectionHandling, BackendError<Self::Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

A client disconnected from the server. This is invoked before authentication has been performed.
source§

fn client_disconnected<'life0, 'life1, 'async_trait>( &'life0 self, client: ConnectedClient<Self>, server: &'life1 CustomServer<Self> ) -> Pin<Box<dyn Future<Output = Result<(), BackendError<Self::Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

A client disconnected from the server.
source§

fn client_authenticated<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, client: ConnectedClient<Self>, session: &'life1 Session, server: &'life2 CustomServer<Self> ) -> Pin<Box<dyn Future<Output = Result<(), BackendError<Self::Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

A client successfully authenticated.
source§

fn client_session_ended<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, session: Session, client: &'life1 ConnectedClient<Self>, disconnecting: bool, server: &'life2 CustomServer<Self> ) -> Pin<Box<dyn Future<Output = Result<(), BackendError<Self::Error>>> + Send + 'async_trait>>where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

A client’s session has ended. Read more
