Enum MirrorStatus 

pub enum MirrorStatus {
    Bootstrapping {
        bytes_done: u64,
        bytes_total: u64,
    },
    Following,
    Degraded {
        lag_ms: u64,
    },
    Disconnected,
    Promoted,
}

Lifecycle status of a mirror database.

Exhaustive matches are required everywhere this enum is matched — no _ => arms.

Variants

Bootstrapping

Initial snapshot transfer is in progress.

Fields

bytes_done: u64

Bytes of snapshot data received so far.

bytes_total: u64

Total snapshot size in bytes (0 = unknown).

Following

Log replication is active; mirror is caught up within normal lag bounds.

Degraded

Mirror is receiving entries but has fallen behind the lag threshold.

Fields

lag_ms: u64

Observed replication lag in milliseconds.

Disconnected

Source is unreachable; mirror is serving stale reads with growing lag.

Promoted

Mirror was promoted to a writable database. Source link is severed. mirror_origin is retained as a historical lineage record.

Trait Implementations

impl Clone for MirrorStatus

fn clone(&self) -> MirrorStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MirrorStatus

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MirrorStatus

fn deserialize<__D>( __deserializer: __D, ) -> Result<MirrorStatus, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for MirrorStatus

fn read<R>(reader: &mut R) -> Result<MirrorStatus, Error>

where R: Read<'__msgpack_de>, MirrorStatus: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for MirrorStatus

fn eq(&self, other: &MirrorStatus) -> 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 Serialize for MirrorStatus

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for MirrorStatus

fn write<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write,

Writes the MessagePack representation of this value into the provided writer.
