Struct SyncState 

pub struct SyncState {
    pub local_head: u64,
    pub remote_head: u64,
    pub last_push: Option<DateTime<Utc>>,
    pub last_pull: Option<DateTime<Utc>>,
    pub pending_count: usize,
}

Tracks the synchronization state between local and remote stores.

This mirrors the JS _ves_sync_state table, keeping track of local/remote heads, push/pull timestamps, and pending event count.

Examples

use stateset_sync::SyncState;

let state = SyncState::default();
assert_eq!(state.local_head, 0);
assert_eq!(state.remote_head, 0);
assert_eq!(state.pending_count, 0);

Fields

local_head: u64

The local head sequence number (last locally recorded event).

remote_head: u64

The remote head sequence number (last known remote sequence).

last_push: Option<DateTime<Utc>>

Timestamp of the last successful push, if any.

last_pull: Option<DateTime<Utc>>

Timestamp of the last successful pull, if any.

pending_count: usize

Number of events pending push.

Implementations

impl SyncState

pub const fn lag(&self) -> u64

Compute the lag (events behind remote).

pub const fn is_synced(&self) -> bool

Whether the local store is in sync with remote.

Trait Implementations

impl Clone for SyncState

fn clone(&self) -> SyncState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncState

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

Formats the value using the given formatter.

impl Default for SyncState

fn default() -> SyncState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SyncState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SyncState

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SyncState
