Struct LocalityInfo 

pub struct LocalityInfo { /* private fields */ }

Resolved failure-domain locality for a single process instance.

Identifiers are globally unique and hierarchical (dc1, dc1-z1, dc1-z1-m1) so that domain queries never confuse a machine in one datacenter with a machine in another.

Implementations

impl LocalityInfo

pub fn new( datacenter: impl Into<String>, zone: impl Into<String>, machine: impl Into<String>, ) -> Self

Create locality from explicit datacenter, zone, and machine ids.

pub fn datacenter(&self) -> &str

The datacenter id (e.g. dc1).

pub fn zone(&self) -> &str

The zone id (e.g. dc1-z1).

pub fn machine(&self) -> &str

The machine id (e.g. dc1-z1-m1).

pub fn id_for(&self, level: DomainLevel) -> &str

The id at the given domain level.

Trait Implementations

impl Clone for LocalityInfo

fn clone(&self) -> LocalityInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocalityInfo

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

Formats the value using the given formatter.

impl Default for LocalityInfo

fn default() -> LocalityInfo

Returns the “default value” for a type.

impl Eq for LocalityInfo

impl PartialEq for LocalityInfo

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