    // Provided method

}

A trait that provides the interface with the device.

Required Methods

fn open( &mut self, geometry: &Geometry, ) -> impl Future<Output = Result<(), LinkError>>

Opens the link.

fn close(&mut self) -> impl Future<Output = Result<(), LinkError>>

Closes the link.

fn alloc_tx_buffer( &mut self, ) -> impl Future<Output = Result<Vec<TxMessage>, LinkError>>

Allocate a sending buffer for the link.

fn send( &mut self, tx: Vec<TxMessage>, ) -> impl Future<Output = Result<(), LinkError>>

Sends a message to the device.

fn receive( &mut self, rx: &mut [RxMessage], ) -> impl Future<Output = Result<(), LinkError>>

Receives a message from the device.

fn is_open(&self) -> bool

Checks if the link is open.

Provided Methods

fn ensure_is_open(&self) -> Result<(), LinkError>

Ensures that the link is open, returning an error if it is not.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
