pub struct Registry<K> { /* private fields */ }

The registry of multiple await-trees.

Implementations

impl<K> Registry<K>

pub fn new(config: Config) -> Self

Create a new registry with given config.

impl<K> Registry<K>where K: Hash + Eq + Debug,

pub fn register(&mut self, key: K, root_span: impl Into<Span>) -> TreeRoot

Register with given key. Returns a TreeRoot that can be used to instrument a future.

If the key already exists, a new TreeRoot is returned and the reference to the old TreeRoot is dropped.

pub fn iter(&self) -> impl Iterator<Item = (&K, TreeContext)>

Iterate over the clones of all registered await-trees.

pub fn get<Q>(&self, k: &Q) -> Option<TreeContext>where K: Borrow<Q>, Q: Hash + Eq + ?Sized,

Get a clone of the await-tree with given key.

Returns None if the key does not exist or the tree root has been dropped.

pub fn clear(&mut self)

Remove all the registered await-trees.
