Enum mz_sql::plan::expr::WindowFrameBound
source · pub enum WindowFrameBound {
UnboundedPreceding,
OffsetPreceding(u64),
CurrentRow,
OffsetFollowing(u64),
UnboundedFollowing,
}
Expand description
Specifies WindowFrame’s start_bound
and end_bound
The order between frame bounds is significant, as Postgres enforces some restrictions there.
