Struct bonsaidb::server::NoBackend

pub struct NoBackend;

A Backend with no custom functionality.

Trait Implementations

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.

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

Invoked once before the server is initialized.

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 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

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

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 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

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

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 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

A client disconnected from the server.

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 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

A client successfully authenticated.

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 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: 'async_trait,

A client’s session has ended.

impl CommandLine for NoBackend

type Backend = NoBackend

The Backend for this command line.

type Subcommand = NoSubcommand

The [Subcommand] which is embedded next to the built-in BonsaiDb commands.

fn configuration<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<ServerConfiguration>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns the server configuration to use when initializing a local server.

fn execute<'life0, 'async_trait>( &'life0 mut self, command: Self::Subcommand, _connection: AnyServerConnection<Self> ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Execute the command on connection.

fn run<'async_trait>( self ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait,

Runs the command-line interface using command-line arguments from the environment.

fn run_from<'async_trait, I, T>( self, itr: I ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where I: IntoIterator<Item = T> + Send + 'async_trait, T: Into<OsString> + Clone + Send + 'async_trait, Self: 'async_trait,

Runs the command-line interface using the specified list of arguments.

fn open_server<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<CustomServer<Self::Backend>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Returns a new server initialized based on the same configuration used for CommandLine.

impl Debug for NoBackend

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

Formats the value using the given formatter.

impl Default for NoBackend

fn default() -> NoBackend

Returns the “default value” for a type.
