Detailed Description

Type used to represent a channel mutable data.

Every channel has a zbus_channel_data structure associated.

Field Documentation

msg_subscriber_pool

struct net_buf_pool* zbus_channel_data::msg_subscriber_pool

Net buf pool for message subscribers.

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

struct k_sem zbus_channel_data::sem

Access control semaphore.

Points to the semaphore used to avoid race conditions for accessing the channel.
