andygrove commented on issue #1804: ARROW-2361: [Rust] Starting point for a
native Rust implementation of Arrow
URL: https://github.com/apache/arrow/pull/1804#issuecomment-377559218
I just implemented the ability to compare two same-typed arrays using
closures. For example:
```
fn test_array_eq() {
let a = Array::from(vec![1,2,3,4,5]);
let b = Array::from(vec![5,4,3,2,1]);
let c = a.compare_array(&b, &|a: i32,b: i32| a == b).unwrap();
assert_eq!(c, vec![false,false,true,false,false]);
}
```
