Struct ReplicationStatus 

pub struct ReplicationStatus {
    pub role: ReplicationRole,
    pub current_lsn: u64,
    pub lag_entries: u64,
    pub lag_ms: u64,
}

Current replication status of a server.

Fields

role: ReplicationRole

Current replication role.

current_lsn: u64

Current LSN (highest written for primary, highest applied for replica).

lag_entries: u64

Replication lag in number of entries (replica only).

lag_ms: u64

Replication lag in milliseconds (replica only).

Implementations

impl ReplicationStatus

pub fn new(role: ReplicationRole, current_lsn: u64) -> Self

Create a new replication status.

pub fn primary(current_lsn: u64) -> Self

Create status for a primary server.

pub fn standalone(current_lsn: u64) -> Self

Create status for a standalone server.

pub fn replica( primary_addr: String, applied_lsn: u64, lag_entries: u64, lag_ms: u64, ) -> Self

Create status for a replica with lag information.

Trait Implementations

impl Archive for ReplicationStatus

where ReplicationRole: Archive, u64: Archive,

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.

type Archived = ArchivedReplicationStatus

The archived representation of this type.

type Resolver = ReplicationStatusResolver

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::Resolver, out: Place<Self::Archived>)

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

impl Clone for ReplicationStatus

fn clone(&self) -> ReplicationStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReplicationStatus

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

Formats the value using the given formatter.

impl Default for ReplicationStatus

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReplicationStatus

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<ReplicationStatus, __D> for Archived<ReplicationStatus>

where ReplicationRole: Archive, <ReplicationRole as Archive>::Archived: Deserialize<ReplicationRole, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>,

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

Deserializes using the given deserializer

impl PartialEq for ReplicationStatus

fn eq(&self, other: &ReplicationStatus) -> 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 ReplicationStatus

where ReplicationRole: Serialize<__S>, u64: 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 ReplicationStatus

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
