Enum tokio_modbus::prelude::Request

A request represents a message from the client (master) to the server (slave).

A poison pill for stopping the client service and to release the underlying transport, e.g. for disconnecting from an exclusively used serial port.

This is an ugly workaround, because tokio-proto does not provide other means to gracefully shut down the ClientService. Otherwise the bound transport is never freed as long as the executor is active, even when dropping the Modbus client context.

Trait Implementations

impl PartialEq<Request> for Request

fn eq(&self, other: &Request) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for Request

impl Clone for Request

fn clone(&self) -> Request

Returns a copy of the value.

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

Performs copy-assignment from source.

impl From<Request> for Bytes

fn from(req: Request) -> Bytes

Performs the conversion.

impl Debug for Request

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

Formats the value using the given formatter.

impl TryFrom<Bytes> for Request

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: Bytes) -> Result<Self, Self::Error>

Performs the conversion.
