Trait for dealing with different types of array at runtime when the type of the array is not known in advance

Required methods

fn as_any(&self) -> &dyn Any

Returns the array as Any so that it can be downcast to a specific implementation

fn data(&self) -> ArrayDataRef

Returns a reference-counted pointer to the data of this array

fn data_ref(&self) -> &ArrayDataRef

Returns a borrowed & reference-counted pointer to the data of this array

Provided methods

fn data_type(&self) -> &DataType

Returns a reference to the data type of this array

fn len(&self) -> usize

Returns the length (i.e., number of elements) of this array

fn offset(&self) -> usize

Returns the offset of this array

fn is_null(&self, i: usize) -> bool

Returns whether the element at index i is null

fn is_valid(&self, i: usize) -> bool

Returns whether the element at index i is not null

fn null_count(&self) -> usize

Returns the total number of nulls in this array
