Struct SyncCursor 

pub struct SyncCursor {
    pub instance_id: InstanceId,
    pub last_sequence: u64,
}

Available on crate feature sync only.

Tracks the sync position for a specific peer instance.

Each peer maintains a cursor recording the last WAL sequence number successfully synced. This enables incremental sync — only changes after the cursor position are transferred.

Fields

instance_id: InstanceId

The peer instance this cursor tracks.

last_sequence: u64

The last WAL sequence number successfully synced from/to this peer.

Implementations

impl SyncCursor

pub fn new(instance_id: InstanceId) -> Self

Creates a new cursor at sequence 0 (beginning of WAL).

Trait Implementations

impl Clone for SyncCursor

fn clone(&self) -> SyncCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncCursor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SyncCursor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SyncCursor

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
