Method bitwise_unary_mut_or_clone

arrow-array/src/array/boolean_array.rs:388–396

Apply a bitwise operation to this array's values in place if the buffer is uniquely owned, or clone and apply if shared. This is a convenience wrapper around [`bitwise_unary_mut`](Self::bitwise_unary_mut) that falls back to [`bitwise_unary`](Self::bitwise_unary) when the buffer is shared. The null buffer is preserved unchanged. # Example ``` # use arrow_array::BooleanArray; let array = Boolean

(self, op: F)

    /// assert_eq!(result, BooleanArray::from(vec![false, true, false]));
    /// ```
    pub fn bitwise_unary_mut_or_clone<F>(self, op: F) -> BooleanArray
    where
        F: FnMut(u64) -> u64,
    {
        match self.try_bitwise_unary_in_place(op) {
            Ok(array) => array,
            Err((array, op)) => array.bitwise_unary(op),
        }
    }

    /// Try to apply a unary op in place. Returns `op` back on failure so
    /// callers can fall back to an allocating path without requiring `F: Clone`.
