impl Coupler

pub async fn connect(addr: SocketAddr) -> Result<Coupler, Error>

Connect to the coupler.

pub async fn disconnect(&mut self) -> Result<(), Error>

Disconnect the coupler.

pub async fn id(&mut self) -> Result<String, Error>

Read the actual coupler ID.

pub fn inputs(&self) -> HashMap<Address, ChannelValue>

Current input state.

pub fn outputs(&self) -> HashMap<Address, ChannelValue>

Current output state.

pub fn modules(&self) -> &[ModuleType]

List of modules.

pub fn set_output( &mut self, addr: &Address, val: ChannelValue, ) -> Result<(), Error>

Set the value of an output channel.

pub fn binary_input_data(&mut self) -> HashMap<Address, Option<Vec<u8>>>

Read binary input data.

pub async fn tick(&mut self) -> Result<(), Error>

Run an I/O cycle. This reads all process input registers and writes to process output registers.
