Struct ResolvedEventRange 

pub struct ResolvedEventRange {
    pub bounds: EventScanBounds,
    pub entry_checkpoint: u64,
    pub end_checkpoint: u64,
    pub end_position: EventPosition,
    pub exhaustion: RangeExhaustion,
}

ResolvedRange’s analogue for event scans: the scan domain is (tx_seq, event_index) coordinates, and the same two endpoint checkpoints annotate it for watermark rendering (see ResolvedRange for why they are not a Range).

Fields

bounds: EventScanBounds

Event-coordinate interval to scan, expressed as explicit lo/hi Bounds (cursor trims need exclusive bounds on either side).

entry_checkpoint: u64

Checkpoint containing the interval’s first position in scan direction; same coverage-clamp role as ResolvedRange::entry_checkpoint.

end_checkpoint: u64

Checkpoint containing end_position; same terminal-frame role as ResolvedRange::end_checkpoint.

end_position: EventPosition

The event coordinate the scan reports when the interval is exhausted (terminal-frame cursor position, paired with end_checkpoint).

exhaustion: RangeExhaustion

Why the interval is exhausted once the scan drains it.

Implementations

impl ResolvedEventRange

pub fn empty_at( end_checkpoint: u64, end_position: EventPosition, exhaustion: RangeExhaustion, ) -> Self

pub fn is_empty(&self) -> bool

pub fn apply_serving_floor( &mut self, floor_tx: u64, floor_checkpoint: u64, options: &QueryOptions, )

ResolvedRange::apply_serving_floor’s analogue for event scans: a floor inside the bounds moves the low bound to the start of the floor transaction (ascending entry rises to the floor checkpoint, a descending terminal is pinned to it); a floor that empties the bounds canonicalizes them to empty at the reported terminal boundary and leaves the terminal metadata at the requested boundary.

Trait Implementations

impl Clone for ResolvedEventRange

fn clone(&self) -> ResolvedEventRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolvedEventRange

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

Formats the value using the given formatter.

impl PartialEq for ResolvedEventRange

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