Struct tokio_zookeeper::WithWatcher
source · pub struct WithWatcher<'a>(_);
Expand description
Proxy for ZooKeeper
that adds non-global watches for initiated operations.
Events from triggered watches are yielded through returned oneshot
channels. All events are
also produced on the global watcher stream.
Implementations§
source§impl<'a> WithWatcher<'a>
impl<'a> WithWatcher<'a>
sourcepub async fn exists(
&self,
path: &str
) -> Result<(Receiver<WatchedEvent>, Option<Stat>), Error>
pub async fn exists( &self, path: &str ) -> Result<(Receiver<WatchedEvent>, Option<Stat>), Error>
Return the Stat
of the node of the given path
, or None
if the node does not exist.
If no errors occur, a watch will be left on the node at the given path
. The watch is
triggered by any successful operation that creates or deletes the node, or sets the data on
the node, and in turn causes the included oneshot::Receiver
to resolve.
sourcepub async fn get_children(
&self,
path: &str
) -> Result<Option<(Receiver<WatchedEvent>, Vec<String>)>, Error>
pub async fn get_children( &self, path: &str ) -> Result<Option<(Receiver<WatchedEvent>, Vec<String>)>, Error>
Return the names of the children of the node at the given path
, or None
if the node
does not exist.
The returned list of children is not sorted and no guarantee is provided as to its natural or lexical order.
If no errors occur, a watch is left on the node at the given path
. The watch is triggered
by any successful operation that deletes the node at the given path
, or creates or
deletes a child of that node, and in turn causes the included oneshot::Receiver
to
resolve.
sourcepub async fn get_data(
&self,
path: &str
) -> Result<Option<(Receiver<WatchedEvent>, Vec<u8>, Stat)>, Error>
pub async fn get_data( &self, path: &str ) -> Result<Option<(Receiver<WatchedEvent>, Vec<u8>, Stat)>, Error>
Return the data and the Stat
of the node at the given path
, or None
if it does not
exist.
If no errors occur, a watch is left on the node at the given path
. The watch is triggered
by any successful operation that sets the node’s data, or deletes it, and in turn causes
the included oneshot::Receiver
to resolve.
