pub fn disjunction(filters: impl IntoIterator<Item = Expr>) -> Option<Expr>Expand description
Combines an array of filter expressions into a single filter expression consisting of the input filter expressions joined with logical OR.
Returns None if the filters array is empty.
ยงExample
// a=1 OR b=2
let expr = col("a").eq(lit(1)).or(col("b").eq(lit(2)));
// [a=1, b=2]
let split = vec![col("a").eq(lit(1)), col("b").eq(lit(2))];
// use disjunction to join them together with `OR`
assert_eq!(disjunction(split), Some(expr));
