Enum RackDistance 

pub enum RackDistance {
    Same,
    SameDc,
    Remote,
}

Coarse-grained proximity classification used by the dispatcher to order replica candidates.

Variants

Same

Same datacenter, same rack.

SameDc

Same datacenter, different rack.

Remote

Different datacenter.

Implementations

impl RackDistance

pub fn cost(self) -> u8

Numeric distance in 0..=2 for sorting.

Examples

use dynomite::cluster::snitch::RackDistance;
assert!(RackDistance::Same.cost() < RackDistance::SameDc.cost());

Trait Implementations

impl Clone for RackDistance

fn clone(&self) -> RackDistance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RackDistance

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

Formats the value using the given formatter.

impl Hash for RackDistance

fn hash<__H: Hasher>(&self, state: &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 PartialEq for RackDistance

fn eq(&self, other: &RackDistance) -> 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.
