Function datafusion_optimizer::utils::split_conjunction_owned
source · pub fn split_conjunction_owned(expr: Expr) -> Vec<Expr>
Expand description
Splits an owned conjunctive Expr
such as A AND B AND C
=> [A, B, C]
This is often used to “split” filter expressions such as col1 = 5 AND col2 = 10
into [col1 = 5
, col2 = 10
];
Example
// a=1 AND b=2
let expr = col("a").eq(lit(1)).and(col("b").eq(lit(2)));
// [a=1, b=2]
let split = vec![
col("a").eq(lit(1)),
col("b").eq(lit(2)),
];
// use split_conjunction_owned to split them
assert_eq!(split_conjunction_owned(expr), split);
