Trait Implementations

impl<State, Context, First, Second> ClientMiddleware<State, Context> for MiddlewareChain<First, Second>

where First: ClientMiddleware<State, Context>, Second: ClientMiddleware<State, Context>,

fn pre_startup( &mut self, context: &Context, state: &mut State, message: PreStartupMessage, ) -> PreStartupMessage

Intercepts a client-originated pre-startup negotiation packet.

fn startup( &mut self, context: &Context, state: &mut State, message: StartupMessage, ) -> StartupMessage

Intercepts the owned startup message before it is sent.

fn frontend( &mut self, context: &Context, state: &mut State, message: FrontendMessage, ) -> FrontendMessage

Intercepts one message sent by the client.

fn backend( &mut self, context: &Context, state: &mut State, message: BackendMessage, ) -> BackendMessage

Intercepts one message received from the server.

impl<First: Clone, Second: Clone> Clone for MiddlewareChain<First, Second>

fn clone(&self) -> MiddlewareChain<First, Second>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<First: Debug, Second: Debug> Debug for MiddlewareChain<First, Second>

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

Formats the value using the given formatter.

impl<First: Eq, Second: Eq> Eq for MiddlewareChain<First, Second>

impl<Context, First, Second> MiddlewareFactory<Context> for MiddlewareChain<First, Second>

where First: MiddlewareFactory<Context>, Second: MiddlewareFactory<Context>,

type Handler = MiddlewareChain<<First as MiddlewareFactory<Context>>::Handler, <Second as MiddlewareFactory<Context>>::Handler>

Handler owned by that connection.

fn create(&self, context: &Context) -> Self::Handler

Creates the handler. Factories are deliberately infallible.

fn eq(&self, other: &MiddlewareChain<First, Second>) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl<State, Context, First, Second> ServerMiddleware<State, Context> for MiddlewareChain<First, Second>

where First: ServerMiddleware<State, Context>, Second: ServerMiddleware<State, Context>,

fn pre_startup( &mut self, context: &Context, state: &mut State, message: PreStartupMessage, ) -> PreStartupMessage

Intercepts one pre-startup packet before protocol dispatch.

fn startup( &mut self, context: &Context, state: &mut State, message: StartupMessage, ) -> StartupMessage

Intercepts the owned startup message before authentication.

fn cancellation( &mut self, context: &Context, state: &mut State, request: CancellationRequest, ) -> CancellationRequest

Intercepts an out-of-band cancellation request before it is returned.

fn frontend( &mut self, context: &Context, state: &mut State, message: FrontendMessage, ) -> FrontendMessage

Intercepts one message received from the client.

fn backend( &mut self, context: &Context, state: &mut State, message: BackendMessage, ) -> BackendMessage

Intercepts one message sent by the server.
