Struct modbus::tcp::Transport

pub struct Transport {
    // some fields omitted
}

Context object which holds state for all modbus operations.

Methods

impl Transport

fn new(addr: &str) -> Result<Transport>

fn new_with_port(addr: &str, port: u16) -> Result<Transport>

Create a new context object and connect it to addr on port port

fn close(self: &mut Self) -> Result<()>
