Window

qbrs_core::window

Struct Window 

Source 
pub struct Window<Req> { /* private fields */ }
Expand description

Accumulates a window’s PARTITION BY/ORDER BY lists, growing Req via Concat as Expr::and/or do — so partitioning by an out-of-scope column fails the same Superset check any other expression would.
