The notification of a change occured on a path/value and reported to a subscription.
See Workspace::subscribe()
and Workspace::subscribe_with_callback()
.
Fields
path: Path
the Path
related to this change.
value: Option<Value>

if the kind is PUT
. None
if the kind is DELETE
.
timestamp: Timestamp
the Timestamp
of the change
kind: ChangeKind
the kind of change (PUT
or DELETE
).
Implementations
impl Change
[src]
pub fn from_sample(sample: Sample, decode_value: bool) -> ZResult<Change>
[src]
Convert a Sample
into a Change
.
If the Sample's kind is DELETE, the Change's value is set to None
.
Otherwise, if decode_value is true
the payload is decoded as a typed Value
.
If decode_value is false
, the payload is converted into a Value::Raw
.
