It can be either the global or a separated one.

◆ observers

sys_slist_t zbus_channel_data::observers

Channel observer list.

Represents the channel's observers list, it can be empty or have listeners and subscribers mixed in any sequence. It can be changed in runtime.

◆ observers_end_idx

int16_t zbus_channel_data::observers_end_idx

Static channel observer list end index.

Considering the ITERABLE SECTIONS allocation order.

◆ observers_start_idx

int16_t zbus_channel_data::observers_start_idx

Static channel observer list start index.

Considering the ITERABLE SECTIONS allocation order.

◆ publish_count

uint32_t zbus_channel_data::publish_count

Number of times data has been published to this channel.

◆ publish_timestamp

k_ticks_t zbus_channel_data::publish_timestamp

Kernel timestamp of the last publish action on this channel.

◆ sem
