Enum TimeTravel 

pub enum TimeTravel {
    Offset(u64),
    TimestampNs(i64),
}

Time-travel coordinate extracted from a SQL string.

Kimberlite supports two forms:

• AT OFFSET <n> (Kimberlite extension) — raw log offset.
• FOR SYSTEM_TIME AS OF '<iso8601>' / AS OF '<iso8601>' (SQL:2011 temporal) — wall-clock timestamp. Resolved to an offset via the audit log’s commit-timestamp index by the caller (see crate::QueryEngine::query_at_timestamp).

AUDIT-2026-04 L-4: the audit flagged the absence of timestamp syntax as a compliance-vertical blocker (healthcare “what did the chart say on 2026-01-15?”, finance point-in-time reporting). This type is the parser-layer landing for both syntaxes; the timestamp→offset resolver is a runtime-layer concern kept separate to avoid the query crate taking a dependency on the audit log.

Variants

Offset(u64)

Raw log offset.

TimestampNs(i64)

Unix-nanosecond timestamp — caller must resolve to an offset.

Trait Implementations

impl Clone for TimeTravel

fn clone(&self) -> TimeTravel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeTravel

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

Formats the value using the given formatter.

impl PartialEq for TimeTravel

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