Struct arrow2_convert::field::LargeVec

pub struct LargeVec<T> { /* private fields */ }

Represents the LargeList Arrow type.

Trait Implementations

impl<T> ArrowDeserialize for LargeVec<T>where T: ArrowDeserialize + ArrowEnableVecForType + 'static, <T as ArrowDeserialize>::ArrayType: 'static, for<'b> &'b <T as ArrowDeserialize>::ArrayType: IntoIterator,

type ArrayType = ListArray<i64>

The arrow2::Array type corresponding to this field

fn arrow_deserialize( v: Option<Box<dyn Array>> ) -> Option<<Self as ArrowField>::Type>

Deserialize this field from arrow

impl<T> ArrowField for LargeVec<T>where T: ArrowField + ArrowEnableVecForType,

type Type = Vec<<T as ArrowField>::Type, Global>

This should be Self except when implementing large offset and fixed placeholder types. For the later, it should refer to the actual type. For example when the placeholder type is LargeString, this should be String.

fn data_type() -> DataType

The DataType

impl<T> ArrowSerialize for LargeVec<T>where T: ArrowSerialize + ArrowEnableVecForType + 'static, <T as ArrowSerialize>::MutableArrayType: Default,

type MutableArrayType = MutableListArray<i64, <T as ArrowSerialize>::MutableArrayType>

The arrow2::array::MutableArray that holds this value

fn new_array() -> Self::MutableArrayType

Create a new mutable array

fn arrow_serialize( v: &<Self as ArrowField>::Type, array: &mut Self::MutableArrayType ) -> Result<()>

Serialize this field to arrow
