Struct WindowSpec 

pub struct WindowSpec {
    pub source: String,
    pub op: String,
    pub partition_by: Vec<String>,
    pub order_by: Option<Order>,
    pub offset: Option<u32>,
    pub alpha: Option<f64>,
    pub frame: Option<Frame>,
}

Fields

source: String

op: String

The aggregate, in the data model’s own vocabulary - see GetFeaturesResp.WindowAggregateArgs. A string rather than an enum so that a View can carry an op the built-in engine has never heard of, e.g. kdb+’s mdev.

partition_by: Vec<String>

order_by: Option<Order>

offset: Option<u32>

alpha: Option<f64>

frame: Option<Frame>

impl WindowSpec

pub fn offset(&self) -> u32

Returns the value of offset, or the default value if offset is unset.

pub fn alpha(&self) -> f64

Returns the value of alpha, or the default value if alpha is unset.
