NullOrder

Enum NullOrder 

Source 
pub enum NullOrder {
    First,
    Last,
}
Expand description

Where NULLs sort relative to non-NULL values. PostgreSQL’s default is NULLS LAST for ASC and NULLS FIRST for DESC; SQLite’s default is NULLS FIRST for both. CrateStack pins the framework default to NULLS LAST so listings stay deterministic across backends and so soft-deleted rows (typed Option<DateTime> that surface as None for visible rows) don’t muscle their way to the top of every listing. Override per-clause via OrderClause::nulls_first when scheduler / outbox queries want fresh-as-null tasks at the head of the queue.

§

fn quirk(&self, value: Quirk) -> Painted<&T>
