Struct PublicOverlayEntriesReadGuard 

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

Methods from Deref<Target = PublicOverlayEntries>

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 iter(&self) -> Values<'_, PeerId, PublicOverlayEntryData>

Returns an iterator over the entries.

The order is not random, but is not defined.

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

where R: Rng + ?Sized,

Returns a reference to one random element of the slice, or None if the slice is empty.

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

where R: Rng + ?Sized,

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

pub fn choose_all<R>( &self, rng: &mut R, ) -> ChooseMultiplePublicOverlayEntries<'_>

where R: Rng + ?Sized,

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