[−][src]Struct arrow::array_data::ArrayData
An generic representation of Arrow array data which encapsulates common attributes and
operations for Arrow array. Specific operations for different arrays types (e.g.,
primitive, list, struct) are implemented in Array
.

buffers: Vec<Buffer>,
child_data: Vec<ArrayDataRef>
) -> Self
pub fn builder(data_type: DataType) -> ArrayDataBuilder
[src]
pub fn builder(data_type: DataType) -> ArrayDataBuilder
Returns a builder to construct a ArrayData
instance.
pub fn data_type(&self) -> &DataType
[src]
pub fn data_type(&self) -> &DataType
Returns a reference to the data type of this array data
pub fn buffers(&self) -> &[Buffer]
[src]
pub fn buffers(&self) -> &[Buffer]
Returns a slice of buffers for this array data
pub fn child_data(&self) -> &[ArrayDataRef]
[src]
pub fn child_data(&self) -> &[ArrayDataRef]
Returns a slice of children data arrays
pub fn is_null(&self, i: i64) -> bool
[src]
pub fn is_null(&self, i: i64) -> bool
Returns whether the element at index i
is null
pub fn null_bitmap(&self) -> &Option<Bitmap>
[src]
pub fn null_bitmap(&self) -> &Option<Bitmap>
Returns a reference to the null bitmap of this array data
pub fn is_valid(&self, i: i64) -> bool
[src]
pub fn is_valid(&self, i: i64) -> bool
Returns whether the element at index i
is not null
pub fn len(&self) -> i64
[src]
pub fn len(&self) -> i64
Returns the length (i.e., number of elements) of this array
pub fn offset(&self) -> i64
[src]
pub fn offset(&self) -> i64
Returns the offset of this array
pub fn null_count(&self) -> i64
[src]
pub fn null_count(&self) -> i64
Returns the total number of nulls in this array
