Method bitwise_unary_mut

arrow-array/src/array/boolean_array.rs:364–370

Try to apply a bitwise operation to this array's values in place using u64 operations. If the underlying buffer is uniquely owned, the operation is applied in place and `Ok` is returned. If the buffer is shared, `Err(self)` is returned so the caller can fall back to [`bitwise_unary`](Self::bitwise_unary). The null buffer is preserved unchanged. # Example ``` # use arrow_array::BooleanArray; le

(self, op: F)

    /// assert_eq!(result, BooleanArray::from(vec![false, true, false]));
    /// ```
    pub fn bitwise_unary_mut<F>(self, op: F) -> Result<BooleanArray, BooleanArray>
    where
        F: FnMut(u64) -> u64,
    {
        self.try_bitwise_unary_in_place(op)
            .map_err(|(array, _op)| array)
    }

    /// Apply a bitwise operation to this array's values in place if the buffer
    /// is uniquely owned, or clone and apply if shared.
