Enum google_api_proto::google::spanner::v1::directed_read_options::Replicas

pub enum Replicas {
    IncludeReplicas(IncludeReplicas),
    ExcludeReplicas(ExcludeReplicas),
}

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

Variants

IncludeReplicas(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 will wait for a replica in the list to become available, requests may fail due to DEADLINE_EXCEEDED errors.

ExcludeReplicas(ExcludeReplicas)

Exclude_replicas indicates that specified replicas should be excluded from serving requests. Spanner will not route requests to the replicas in this list.

Implementations

impl Replicas

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<Replicas>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for Replicas

fn clone(&self) -> Replicas

Returns a copy 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

This method tests for self and other values to be equal, and is used by ==.

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

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