Trait InstanceServerHandler 

pub trait InstanceServerHandler<___T = Channel>
where
    ___T: Transport,
{
    // Required method
    fn add_line(
        &mut self,
        request: Request<AddLine, ___T>,
        responder: Responder<AddLine, ___T>,
    ) -> impl Future<Output = ()> + Send;

    // Provided method
    fn on_unknown_interaction(
        &mut self,
        ordinal: u64,
    ) -> impl Future<Output = ()> + Send { ... }
}

A server handler for the Instance protocol.

See Instance for more details.

Required Methods

fn add_line( &mut self, request: Request<AddLine, ___T>, responder: Responder<AddLine, ___T>, ) -> impl Future<Output = ()> + Send

Add a line to the canvas.

This method can be considered an improvement over the one-way case from a flow control perspective, as it is now much more difficult for a well-behaved client to “get ahead” of the server and overwhelm. This is because the client now waits for each request to be acked by the server before proceeding. This change represents a trade-off: we get much greater synchronization of message flow between the client and the server, at the cost of worse performance at the limit due to the extra wait imposed by each ack.

Provided Methods

fn on_unknown_interaction( &mut self, ordinal: u64, ) -> impl Future<Output = ()> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
