Struct SyncRow 

pub struct SyncRow {
    pub sequence: u64,
    pub action: SyncAction,
}

One sync log row with monotonic sequence metadata.

Fields

sequence: u64

Monotonic sequence number assigned by the extension.

action: SyncAction

Action to replay.

Implementations

impl SyncRow

pub fn apply_in_order( rows: &[Self], overlay: &mut OverlayState, ) -> Result<usize, PostgresGraphError>

Applies rows to overlay in strictly increasing sequence order.

Errors

Returns PostgresGraphError::Sync when rows are out of order.

Performance

This method is O(r log r + a) where r is row count and a is applied actions.

Trait Implementations

impl Clone for SyncRow

fn clone(&self) -> SyncRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyncRow

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

Formats the value using the given formatter.

impl PartialEq for SyncRow

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