Trait SliceAccessor

pub trait SliceAccessor {
    // Required method
    fn range(self, start: Expr, stop: Expr) -> Expr;
}

Expand description

Return elements between 1 based start and stop, for example expr[1:3]

For example if column “c1” holds documents like this

[10, 20, 30, 40]

You can access the value [20, 30, 40] with

let expr = col("c1").range(lit(2), lit(4));
assert_eq!(expr.schema_name().to_string(), "c1[Int32(2):Int32(4)]");
