[−][src]Struct arrow::array::ListArray
A list array where each element is a variable-sized sequence of values with the same type.
Methods
impl ListArray[src]
impl ListArraypub fn values(&self) -> ArrayRef[src]
pub fn values(&self) -> ArrayRefReturns an reference to the values of this list.
pub fn value_type(&self) -> DataType[src]
pub fn value_type(&self) -> DataTypeReturns a clone of the value type of this list.
pub fn value_offset(&self, i: i64) -> i32[src]
pub fn value_offset(&self, i: i64) -> i32Returns the offset for value at index i.
Note this doesn't do any bound checking, for performance reason.
pub fn value_length(&self, i: i64) -> i32[src]
pub fn value_length(&self, i: i64) -> i32Returns the length for value at index i.
Note this doesn't do any bound checking, for performance reason.
Trait Implementations
impl Array for ListArray[src]
impl Array for ListArrayfn as_any(&self) -> &dyn Any[src]
fn as_any(&self) -> &dyn AnyReturns the array as Any so that it can be downcast to a specific implementation
fn data(&self) -> ArrayDataRef[src]
fn data(&self) -> ArrayDataRefReturns a reference-counted pointer to the data of this array
fn data_ref(&self) -> &ArrayDataRef[src]
fn data_ref(&self) -> &ArrayDataRefReturns a borrowed & reference-counted pointer to the data of this array
fn data_type(&self) -> &DataType[src]
fn data_type(&self) -> &DataTypeReturns a reference to the data type of this array
fn len(&self) -> i64[src]
fn len(&self) -> i64Returns the length (i.e., number of elements) of this array
fn offset(&self) -> i64[src]
fn offset(&self) -> i64Returns the offset of this array
fn is_null(&self, i: i64) -> bool[src]
fn is_null(&self, i: i64) -> boolReturns whether the element at index i is null
fn is_valid(&self, i: i64) -> bool[src]
fn is_valid(&self, i: i64) -> boolReturns whether the element at index i is not null
fn null_count(&self) -> i64[src]
fn null_count(&self) -> i64Returns the total number of nulls in this array
impl From<Arc<ArrayData>> for ListArray[src]
impl From<Arc<ArrayData>> for ListArrayConstructs a ListArray from an array data reference.
fn from(data: ArrayDataRef) -> Self[src]
fn from(data: ArrayDataRef) -> SelfPerforms the conversion.
