Enum bonsaidb_server::NoBackend

pub enum NoBackend {}

A Backend with no custom functionality.

Trait Implementations

impl Backend for NoBackend

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.

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.

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

Invoked once before the server is initialized.

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

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

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

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

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

A client disconnected from the server.

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

A client successfully authenticated.

impl Debug for NoBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for NoBackend

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches<'b>(
    &mut self,
    __clap_arg_matches: &ArgMatches
) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Subcommand for NoBackend

fn augment_subcommands<'b>(__clap_app: Command<'b>) -> Command<'b>

Append to Command so it can instantiate Self.

fn augment_subcommands_for_update<'b>(__clap_app: Command<'b>) -> Command<'b>

Append to Command so it can update self.

fn has_subcommand(__clap_name: &str) -> bool

Test whether Self can parse a specific subcommand
