Struct ModbusRtuOverTcpServer 

pub struct ModbusRtuOverTcpServer<S> { /* private fields */ }

Modbus RTU-over-TCP server that accepts TCP connections carrying RTU-framed requests.

This is useful for RTU gateways or testing environments where RTU framing is tunnelled over a TCP socket.

Implementations

impl<S: ModbusService> ModbusRtuOverTcpServer<S>

pub async fn bind<A: ToSocketAddrs>( addr: A, service: S, ) -> Result<Self, DataLinkError>

Bind to a TCP address and create a new RTU-over-TCP server.

pub fn from_listener(listener: TcpListener, service: S) -> Self

Create a server from an existing TcpListener.

pub fn local_addr(&self) -> Result<SocketAddr, DataLinkError>

Return the local address the server is bound to.

pub fn with_max_pdu_len(self, max_pdu_len: usize) -> Self

Set the maximum PDU length (default: 253).

pub fn with_max_frame_len(self, max_frame_len: usize) -> Self

Set the maximum RTU frame length including address + CRC (default: 256).

pub fn with_max_connections(self, max_connections: usize) -> Self

Set the maximum number of concurrent client connections (default: 256).

pub async fn run(self) -> Result<(), DataLinkError>

Accept connections and serve requests indefinitely.

pub async fn run_until( self, shutdown: impl Future<Output = ()> + Send, ) -> Result<(), DataLinkError>

Run the server until the given shutdown future completes.
