pub struct WindowFrame {
    pub units: WindowFrameUnits,
    pub start_bound: WindowFrameBound,
    pub end_bound: WindowFrameBound,
}
Expand description

Describe a window frame, e.g. RANGE UNBOUNDED PRECEDING or ROWS BETWEEN 5 PRECEDING AND CURRENT ROW.

Window frames define a subset of the partition , and only a subset of window functions make use of the window frame.

Fields

units: WindowFrameUnits

ROWS, RANGE or GROUPS

start_bound: WindowFrameBound

Where the frame starts

end_bound: WindowFrameBound

Where the frame ends

Implementations

Return the default window frame used when one is not explicitly defined
