Struct VirtualNode 

pub struct VirtualNode<N>
where
    N: Node + ?Sized,
{ /* private fields */ }

A type to represent a single virtual node of a distinct Node in the consistent hashing ring.

Implementations

impl<N> VirtualNode<N>

where N: Node + ?Sized,

pub fn replica_owners(&self) -> &[Arc<N>]

Returns a slice of Nodes, each wrapped in an Arc, which own a replica for the keys that are assigned on the VirtualNode<N> at hand.

The Nodes are returned according to their order in the consistent hashing ring. Therefore, the first Node is always the one that the particular VirtualNode originally belongs to.

Trait Implementations

impl<N> AsRef<[u8]> for VirtualNode<N>

where N: Node + ?Sized,

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<N> Borrow<[u8]> for VirtualNode<N>

where N: Node + ?Sized,

fn borrow(&self) -> &[u8]

Immutably borrows from an owned value.

impl<N> Clone for VirtualNode<N>

where N: Node + ?Sized,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N> Debug for VirtualNode<N>

where N: Node + ?Sized + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<N> Display for VirtualNode<N>

where N: Node + ?Sized,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<N> Hash for VirtualNode<N>

where N: Node + ?Sized,

fn hash<H: StdHasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<N> Ord for VirtualNode<N>

where N: Node + ?Sized,

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<N> PartialEq for VirtualNode<N>

where N: Node + ?Sized,

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<N> PartialOrd for VirtualNode<N>

where N: Node + ?Sized,

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
