Detailed Description

Gives a writer entity the write API of the WriterDevice it owns.

The device is a member, not a base: the mixin declares no virtual function, so an entity mixing it in gains no second vtable and all the writer platforms share the single WriterDevice vtable instead of each emitting its own copy. The forwarders keep item->write_*() working unchanged inside a write_lambda, and record every dispatch, so the write path can tell "the lambda sent it itself" from "use the default write".

clear_dispatched_()

void esphome::modbus_controller::WriterEntity::clear_dispatched_ ( )

inlineprotected

Definition at line 361 of file modbus_controller.h.

clear_tx_queue_for_device()

void esphome::modbus_controller::WriterEntity::clear_tx_queue_for_device ( )

dispatched()

bool esphome::modbus_controller::WriterEntity::dispatched ( ) const

inline

Whether the lambda called a request helper since the last clear_dispatched_().

Deliberately records the call, not the hub's accept/refuse: a refused lambda write must not fall through to the default write.
