Function lt

pub fn lt(lhs: ExprRef, rhs: ExprRef) -> ExprRef

Create a new BinaryExpr using the Lt operator.

Example usage

use vortex_array::arrays::{BoolArray, PrimitiveArray };
use vortex_array::{IntoArray, ToCanonical};
use vortex_array::validity::Validity;
use vortex_buffer::buffer;
use vortex_expr::{root, lit, lt, Scope};

let xs = PrimitiveArray::new(buffer![1i32, 2i32, 3i32], Validity::NonNullable);
let result = lt(root(), lit(3)).evaluate(&Scope::new(xs.to_array())).unwrap();

assert_eq!(
    result.to_bool().unwrap().boolean_buffer(),
    BoolArray::from_iter(vec![true, true, false]).boolean_buffer(),
);
