Function concat_elements_utf8

arrow-string/src/concat_elements.rs:89–94

Returns the elementwise concatenation of a [`GenericStringArray`]. An index of the resulting [`GenericStringArray`] is null if any of `StringArray` are null at that location. ```text e.g: ["Hello"] + ["World"] = ["HelloWorld"] ["a", "b"] + [None, "c"] = [None, "bc"] ``` An error will be returned if `left` and `right` have different lengths

(
    left: &GenericStringArray<Offset>,
    right: &GenericStringArray<Offset>,
)
