Detailed Description

Mutable counterpart of PackedBits: set() writes bits in place (deliberately no proxy operator[]=).

Converts implicitly to PackedBits for read access.

Member Function Documentation

operator PackedBits()

esphome::modbus::MutablePackedBits::operator PackedBits ( ) const

inline

Definition at line 189 of file modbus_definitions.h.

operator[]()

bool esphome::modbus::MutablePackedBits::operator[] ( size_t bit ) const

inline

Definition at line 176 of file modbus_definitions.h.

set()

void esphome::modbus::MutablePackedBits::set ( size_t bit, bool value )

inline

Set or clear the given bit.

Out-of-range bits are dropped: on the server read path the span wraps a stack response buffer, so a handler looping past size() must not be able to smash the frame.

size()

uint16_t esphome::modbus::MutablePackedBits::size ( ) const
