Struct NodeWorkerCheckpoint 

pub struct NodeWorkerCheckpoint {
    pub partition: CrossNodePartition,
    pub rank: usize,
    pub next_ordinal: usize,
}

Serialized cursor of one worker: everything needed for a replacement process (same rank, any host) to continue the dead worker’s deterministic chunk sequence from where receipts stopped. Pure data; the worker’s row source re-seeks by row range, which is a pure function of the partition.

Fields

partition: CrossNodePartition

rank: usize

next_ordinal: usize

Ordinal (into the rank’s owned-chunk sequence) of the next chunk to compute and ship. Everything below it has been durably shipped.

Trait Implementations

impl Clone for NodeWorkerCheckpoint

fn clone(&self) -> NodeWorkerCheckpoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NodeWorkerCheckpoint

impl Debug for NodeWorkerCheckpoint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeWorkerCheckpoint

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for NodeWorkerCheckpoint

impl PartialEq for NodeWorkerCheckpoint

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
