Struct Frame 

pub struct Frame {
    pub options: i32,
    pub start: Option<Expr>,
    pub end: Option<Expr>,
    pub start_in_range: u32,
    pub end_in_range: u32,
    pub in_range_asc: bool,
    pub in_range_nulls_first: bool,
}

The frame of a window, as the fields frameOptions, startOffset, endOffset, startInRangeFunc, endInRangeFunc, inRangeAsc and inRangeNullsFirst of WindowClause.

Fields

options: i32

frameOptions: the bits FRAMEOPTION_* of the mode, the bounds and the exclusion.

start: Option<Expr>

The offset of the start, of type bigint in ROWS and GROUPS mode.

end: Option<Expr>

The offset of the end, of type bigint in ROWS and GROUPS mode.

start_in_range: u32

startInRangeFunc: the in_range function of the start in RANGE mode with an offset, or 0.

end_in_range: u32

endInRangeFunc: the in_range function of the end in RANGE mode with an offset, or 0.

in_range_asc: bool

inRangeAsc: true when the column of ORDER BY sorts in ascending order.

in_range_nulls_first: bool

inRangeNullsFirst: true when the nulls of the column of ORDER BY come first.

Implementations

impl Frame

pub fn mode(&self) -> FrameMode

The mode of the frame.

pub fn start_bound(&self) -> FrameBound

The start of the frame.

pub fn end_bound(&self) -> FrameBound

The end of the frame.

pub fn exclusion(&self) -> FrameExclusion

The rows that the frame does not have.
