Type Alias StringViewArray

pub type StringViewArray = GenericByteViewArray<StringViewType>;

A GenericByteViewArray that stores utf8 data

See GenericByteViewArray for format and layout details.

Example

use arrow_array::StringViewArray;
let array = StringViewArray::from_iter_values(vec!["hello", "world", "lulu", "large payload over 12 bytes"]);
assert_eq!(array.value(0), "hello");
assert_eq!(array.value(3), "large payload over 12 bytes");
