Trait tokio_modbus::server::Service

pub trait Service {
    type Request;
    type Response: Into<Option<Response>>;
    type Exception: Into<Exception>;
    type Future: Future<Output = Result<Self::Response, Self::Exception>> + Send;

    // Required method
    fn call(&self, req: Self::Request) -> Self::Future;
}

A Modbus server service.

Required Associated Types

type Request

Requests handled by the service.

Both tokio_modbus::Request and tokio_modbus::SlaveRequest are possible choices.

type Response: Into<Option<Response>>

Responses sent by the service.

Both tokio_modbus::Response and Option<tokio_modbus::Response> are possible choices. The latter allows to selectively ignore requests by not sending a response.

type Exception: Into<Exception>

Exceptional responses sent by the service.

Use tokio_modbus::Exception as default.

type Future: Future<Output = Result<Self::Response, Self::Exception>> + Send

The future response value.

Required Methods

fn call(&self, req: Self::Request) -> Self::Future

Process the request and return the response asynchronously.
