Struct ScoreScanOrder 

pub struct ScoreScanOrder {
    pub alias: String,
    pub ascending: bool,
    pub nulls_first: bool,
}

The order a bounded score scan keeps its best rows in: one score column.

Fields

alias: String

Alias of the score column the rows are ordered by.

ascending: bool

nulls_first: bool

Whether null scores sort before every number.
