source · [−]

pub enum Entry<'a, TPeerId, TVal> {
    Present(PresentEntry<'a, TPeerId, TVal>, NodeStatus),

Expand description

A reference into a single entry of a KBucketsTable.

Variants

`Present(PresentEntry<'a, TPeerId, TVal>, NodeStatus)`

The entry is present in a bucket.

`Pending(PendingEntry<'a, TPeerId, TVal>, NodeStatus)`

The entry is pending insertion in a bucket.

`Absent(AbsentEntry<'a, TPeerId, TVal>)`

The entry is absent and may be inserted.

`SelfEntry`

The entry represents the local node.

Implementations

impl<'a, TKey, TVal> Entry<'a, TKey, TVal> where
TKey: Clone + AsRef<KeyBytes>,
TVal: Clone,

pub fn view(&'a mut self) -> Option<EntryRefView<'a, TKey, TVal>>

Creates an immutable by-reference view of the entry.

Returns None if the entry is neither present in a bucket nor pending insertion into a bucket.

pub fn key(&self) -> Option<&TKey>

Returns the key of the entry.

Returns None if the Key used to construct this Entry is not a valid key for an entry in a bucket, which is the case for the local_key of the KBucketsTable referring to the local node.

pub fn value(&mut self) -> Option<&mut TVal>

Returns the value associated with the entry.

Returns None if the entry is absent from any bucket or refers to the local node.
