Method bitwise_unary

arrow-array/src/array/boolean_array.rs:334–345

Apply a bitwise operation to this array's values using u64 operations, returning a new [`BooleanArray`]. The null buffer is preserved unchanged. See [`BooleanBuffer::from_bitwise_unary_op`] for details on the operation. # Example ``` # use arrow_array::BooleanArray; let array = BooleanArray::from(vec![true, false, true]); let result = array.bitwise_unary(|x| !x); assert_eq!(result, BooleanArra

(&self, op: F)

    /// assert_eq!(result, BooleanArray::from(vec![false, true, false]));
    /// ```
    pub fn bitwise_unary<F>(&self, op: F) -> BooleanArray
    where
        F: FnMut(u64) -> u64,
    {
        let values = BooleanBuffer::from_bitwise_unary_op(
            self.values.values(),
            self.values.offset(),
            self.values.len(),
            op,
        );
        BooleanArray::new(values, self.nulls.clone())
    }

    /// Try to apply a bitwise operation to this array's values in place using
    /// u64 operations.
