Struct NodeManagersRef

pub struct NodeManagersRef { /* private fields */ }

A weak reference to the node manager collection.

Implementations

impl NodeManagersRef

pub fn upgrade(&self) -> Option<NodeManagers>

Upgrade this node manager ref. Note that node managers should avoid keeping a permanent copy of the NodeManagers struct, to avoid circular references leading to a memory leak when the server is dropped.

If this fails, it means that the server is dropped, so feel free to abort anything going on.

pub fn iter(&self) -> impl Iterator<Item = Arc<DynNodeManager>>

Iterate over node managers. If the server is dropped this iterator will be empty.

pub fn get_of_type<T: NodeManager + Send + Sync + Any>(&self) -> Option<Arc<T>>

Get the first node manager with the specified type.

pub fn get_by_name<T: NodeManager + Send + Sync + Any>( &self, name: &str, ) -> Option<Arc<T>>

Get the first node manager with the specified name and try to cast it to the type T.

If there are multiple node managers with the same name, only the first will ever be returned by this. Avoid having duplicate node managers.

pub fn get(&self, index: usize) -> Option<Arc<DynNodeManager>>

Get the node manager at the specified index.
