Struct datafusion::logical_expr::window_state::WindowFrameStateRange

source · 
pub struct WindowFrameStateRange { /* private fields */ }
Expand description

This structure encapsulates all the state information we require as we scan ranges of data while processing RANGE frames. Attribute sort_options stores the column ordering specified by the ORDER BY clause. This information is used to calculate the range.
