Method lengths

arrow-array/src/array/byte_view_array.rs:457–459

Return an iterator over the length of each array element, including null values. Null values length would equal to the underlying bytes length and NOT 0 Example of getting 0 for null values ```rust # use arrow_array::StringViewArray; # use arrow_array::Array; use arrow_data::ByteView; fn lengths_with_zero_for_nulls(view: &StringViewArray) -> impl Iterator { view.lengths() .enumerate

(&self)

    /// }
    /// ```
    pub fn lengths(&self) -> impl ExactSizeIterator<Item = u32> + Clone {
        self.views().iter().map(|v| *v as u32)
    }

    /// Returns a zero-copy slice of this array with the indicated offset and length.
    pub fn slice(&self, offset: usize, length: usize) -> Self {
