Expand description

Perform SQL left LIKE right

There are two wildcards supported with the LIKE operator:

  1. % - The percent sign represents zero, one, or multiple characters
  2. _ - The underscore represents a single character

For example:

let strings = StringArray::from(vec!["Arrow", "Arrow", "Arrow", "Ar"]);
let patterns = StringArray::from(vec!["A%", "B%", "A.", "A_"]);

let result = like(&strings, &patterns).unwrap();
assert_eq!(result, BooleanArray::from(vec![true, false, false, true]));
