Enum Replicas 

#[non_exhaustive]
pub enum Replicas {
    IncludeReplicas(Box<IncludeReplicas>),
    ExcludeReplicas(Box<ExcludeReplicas>),
}

Required. At most one of either include_replicas or exclude_replicas should be present in the message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IncludeReplicas(Box<IncludeReplicas>)

Include_replicas indicates the order of replicas (as they appear in this list) to process the request. If auto_failover_disabled is set to true and all replicas are exhausted without finding a healthy replica, Spanner waits for a replica in the list to become available, requests might fail due to DEADLINE_EXCEEDED errors.

ExcludeReplicas(Box<ExcludeReplicas>)

Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner doesn’t route requests to the replicas in this list.

Implementations

impl Replicas

pub fn from_include_replicas(value: impl Into<Box<IncludeReplicas>>) -> Self

Initializes the enum to the IncludeReplicas branch.

pub fn from_exclude_replicas(value: impl Into<Box<ExcludeReplicas>>) -> Self

Initializes the enum to the ExcludeReplicas branch.

Trait Implementations

impl Clone for Replicas

fn clone(&self) -> Replicas

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Replicas

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

Formats the value using the given formatter.

impl PartialEq for Replicas

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