Enum ReplicationRole 

pub enum ReplicationRole {
    Primary,
    Replica {
        primary_addr: String,
    },
    Standalone,
}

Replication role of a server instance.

Variants

Primary

Primary server - accepts writes.

Replica

Replica server - read-only, replicates from primary.

Fields

primary_addr: String

Address of the primary server.

Standalone

Standalone server - not participating in replication.

Implementations

impl ReplicationRole

pub fn can_write(&self) -> bool

Check if this role allows writes.

pub fn is_replica(&self) -> bool

Check if this is a replica.

pub fn is_primary(&self) -> bool

Check if this is the primary.

Trait Implementations

impl Archive for ReplicationRole

where String: Archive,

type Archived = ArchivedReplicationRole

The archived representation of this type.

type Resolver = ReplicationRoleResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for ReplicationRole

fn clone(&self) -> ReplicationRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicationRole

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

Formats the value using the given formatter.

impl Default for ReplicationRole

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReplicationRole

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<ReplicationRole, __D> for Archived<ReplicationRole>

where String: Archive, <String as Archive>::Archived: Deserialize<String, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ReplicationRole, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl PartialEq for ReplicationRole

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

impl<__S: Fallible + ?Sized> Serialize<__S> for ReplicationRole

where String: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for ReplicationRole

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
