Struct MachineRegistry 

pub struct MachineRegistry { /* private fields */ }

Registry mapping process IPs to their resolved locality.

Parallel to TagRegistry but for failure domains: supports shared-fate queries (all IPs on a machine, in a zone, or in a datacenter).

Implementations

impl MachineRegistry

pub fn new() -> Self

Create an empty registry.

pub fn register(&mut self, ip: IpAddr, locality: LocalityInfo)

Register locality for a process IP.

pub fn is_empty(&self) -> bool

Whether any locality has been registered.

pub fn locality_for(&self, ip: IpAddr) -> Option<&LocalityInfo>

Get the locality for a specific IP.

pub fn ips_in_domain(&self, level: DomainLevel, id: &str) -> Vec<IpAddr>

Find all IPs whose domain at level matches id.

pub fn ips_on_machine(&self, machine_id: &str) -> Vec<IpAddr>

Find all IPs on a single machine — the unit of shared fate.

pub fn all_machines(&self) -> Vec<String>

All distinct machine ids, sorted for determinism.

pub fn all_zones(&self) -> Vec<String>

All distinct zone ids, sorted for determinism.

pub fn all_datacenters(&self) -> Vec<String>

All distinct datacenter ids, sorted for determinism.

Trait Implementations

impl Clone for MachineRegistry

fn clone(&self) -> MachineRegistry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MachineRegistry

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

Formats the value using the given formatter.

impl Default for MachineRegistry

fn default() -> MachineRegistry

Returns the “default value” for a type.

impl PartialEq for MachineRegistry

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