Trait Client

Transport independent asynchronous client trait

Required Methods

fn call<'life0, 'life1, 'async_trait>( &'life0 mut self, request: Request<'life1>, ) -> Pin<Box<dyn Future<Output = Result<Response>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Invokes a Modbus function.

fn disconnect<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Disconnects the client.

Permanently disconnects the client by shutting down the underlying stream in a graceful manner (AsyncDrop).

Dropping the client without explicitly disconnecting it beforehand should also work and free all resources. The actual behavior might depend on the underlying transport protocol (RTU/TCP) that is used by the client.
