Struct google_firestore1_beta1::TargetChange

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

Targets being watched have changed.

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

Fields

target_change_type: Option<String>

The type of change that occurred.

resume_token: Option<String>

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.

cause: Option<Status>

The error that resulted in this change, if applicable.

target_ids: Option<Vec<i32>>

The target IDs of targets that have changed.

If empty, the change applies to all targets.

For target_change_type=ADD, the order of the target IDs matches the order of the requests to add the targets. This allows clients to unambiguously associate server-assigned target IDs with added targets.

For other states, the order of the target IDs is not defined.

read_time: Option<String>

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.
