Struct PrivateOverlayEntriesWriteGuard 

pub struct PrivateOverlayEntriesWriteGuard<'a> { /* private fields */ }

Implementations

impl<'a> PrivateOverlayEntriesWriteGuard<'a>

pub fn downgrade(self) -> PrivateOverlayEntriesReadGuard<'a>

Methods from Deref<Target = PrivateOverlayEntries>

pub fn subscribe(&self) -> Receiver<PrivateOverlayEntriesEvent>

Subscribes to the set updates.

pub fn iter(&self) -> Values<'_, PeerId, PrivateOverlayEntryData>

Returns an iterator over the entry ids.

The order is not random, but is not defined.

pub fn choose<R>(&self, rng: &mut R) -> Option<&PrivateOverlayEntryData>

where R: Rng + ?Sized,

Returns one random peer, or None if set is empty.

pub fn choose_multiple<R>( &self, rng: &mut R, n: usize, ) -> ChooseMultiplePrivateOverlayEntries<'_>

where R: Rng + ?Sized,

Chooses n entries from the set, without repetition, and in random order.

pub fn clear(&mut self)

Clears the set, removing all entries.

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

pub fn len(&self) -> usize

Returns the number of elements in the set, also referred to as its ‘length’.

pub fn contains(&self, peer_id: &PeerId) -> bool

Returns true if the set contains the specified peer id.

pub fn get_handle(&self, peer_id: &PeerId) -> Option<&PeerResolverHandle>

Returns the peer resolver handle for the specified peer id, if it exists.

pub fn insert(&mut self, peer_id: &PeerId) -> bool

Adds a peer id to the set.

Returns whether the value was newly inserted.

pub fn remove(&mut self, peer_id: &PeerId) -> bool

Removes a value from the set.

Returns whether the value was present in the set.
