    DrainingWal,
    SyncingRedis,
    WarmingUp,
    Ready,
    Running,
    ShuttingDown,
}

Engine lifecycle state.

The engine progresses through states during startup and shutdown. Use super::SyncEngine::state() to check current state or super::SyncEngine::state_receiver() to watch for changes.

Variants

Created

Just created, not yet started

Connecting

Connecting to backends (L2/L3)

DrainingWal

Draining WAL to SQL (blocking, before accepting writes)

SyncingRedis

Syncing Redis from SQL (branch diff)

WarmingUp

Warming up cuckoo filters

Ready

Ready to accept data

Running

Running normally

ShuttingDown

Graceful shutdown in progress

Trait Implementations

impl Clone for EngineState

fn clone(&self) -> EngineState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineState

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

Formats the value using the given formatter.

impl Display for EngineState

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

Formats the value using the given formatter.

impl PartialEq for EngineState

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