Struct ProjectionCursor 

pub struct ProjectionCursor {
    pub sequence: u64,
    pub tick: Tick,
}

Composite event-stream position. EventRecord.sequence is per-compute — it restarts at 0 for every action’s ActionContext — so an event is identified in the stream by the (tick, sequence) pair, ordered tick-major.

Fields

sequence: u64

Sequence number within the emitting compute’s batch.

tick: Tick

Tick at which the event was emitted.

Trait Implementations

impl Clone for ProjectionCursor

fn clone(&self) -> ProjectionCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProjectionCursor

impl Debug for ProjectionCursor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProjectionCursor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ProjectionCursor

impl PartialEq for ProjectionCursor

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
