Struct TargetChange

pub struct TargetChange {
    pub cause: Option<Status>,
    pub read_time: Option<DateTime<Utc>>,
    pub resume_token: Option<Vec<u8>>,
    pub target_change_type: Option<String>,
    pub target_ids: Option<Vec<i32>>,
}

Targets being watched have changed.

This type is not used in any activity, and only used as part of another schema.

Fields

cause: Option<Status>

The error that resulted in this change, if applicable.

read_time: Option<DateTime<Utc>>

The consistent read_time for the given target_ids (omitted when the target_ids are not at a consistent snapshot). The stream is guaranteed to send a read_time with target_ids empty whenever the entire stream reaches a new consistent snapshot. ADD, CURRENT, and RESET messages are guaranteed to (eventually) result in a new consistent snapshot (while NO_CHANGE and REMOVE messages are not). For a given stream, read_time is guaranteed to be monotonically increasing.

resume_token: Option<Vec<u8>>

A token that can be used to resume the stream for the given target_ids, or all targets if target_ids is empty. Not set on every target change.

target_change_type: Option<String>

The type of change that occurred.

target_ids: Option<Vec<i32>>

The target IDs of targets that have changed. If empty, the change applies to all targets. The order of the target IDs is not defined.
