Struct GraphQueryWindow 

pub struct GraphQueryWindow {
    observed_start_ms: i64,
    observed_end_ms: i64,
    source_start_ms: i64,
    source_end_ms: i64,
}

The read-time query window, resolved from the scan’s observed_at predicate (or the product default). Two half-open [start, end) millisecond ranges:

• observed: the queried observed_at range. The scan’s filters are re-applied above the computed table (FilterPushDownType::Inexact), so every emitted row’s observed_at must fall inside it. The declared-edge branch also runs its validity overlap against this range.
• source scan: observed widened to whole 60s buckets. Derived rows are date_bin('60s') aggregates keyed by the bucket start, so a bucket the observed range selects must be scanned over its full extent — filtering the source rows to the observed range instead would silently truncate the RED numbers of the boundary buckets.

The bounds are plain millisecond values turned into timestamp literals on demand — wall-clock snapshot semantics like now(), but as constants they prune the source table scans without depending on constant-folding.

source_start_ms: i64

source_end_ms: i64

Implementations

impl GraphQueryWindow

pub fn from_observed(start_ms: i64, end_ms: i64) -> Self

Builds the window for the queried observed_at range [start_ms, end_ms).

pub fn default_last_hour() -> Self

Conservative default when a query carries no explicit time predicate: the last hour, so a bare SELECT * FROM semantic_entities never scans every declaring table’s full history. This is a product default, not a cap.

pub fn observed_start(&self) -> Expr

Start of the queried observed_at range (inclusive).

pub fn observed_end(&self) -> Expr

End of the queried observed_at range (exclusive).

pub fn source_start(&self) -> Expr

Start of the source-table scan range (inclusive).

pub fn source_end(&self) -> Expr

End of the source-table scan range (exclusive).

Trait Implementations

impl Clone for GraphQueryWindow

fn clone(&self) -> GraphQueryWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphQueryWindow

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

Formats the value using the given formatter.
